<br />
== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners' guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disable KMS ===<br />
<br />
To avoid getting a blank screen during installation, you should disable KMS ([[Kernel mode setting]]). This can be done as follows: when booting from the USB stick, on the Arch Linux boot menu, press {{ic|e}} and then type {{ic|nomodeset}}. Finally, press enter to boot without KMS.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners' guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of at least 100MB (specify size: {{ic|100M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners' guide]].<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners' guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
Useful GNOME extensions:<br />
<br />
* [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher]<br />
<br />
* [https://extensions.gnome.org/extension/584/taskbar/ TaskBar]<br />
<br />
* [https://extensions.gnome.org/extension/495/topicons/ TopIcons]<br />
<br />
How to show date next to the clock:<br />
<br />
* Run {{ic|dconf-editor}} and open org>gnome>desktop>interface. Select clock-show-date.<br />
<br />
How to make thunderbird the default calendar:<br />
<br />
* Edit {{ic|/usr/share/applications/thunderbird.desktop}} and append {{ic|text/calendar;text/x-vcard;}} to MimeType. Then run {{ic|sudo update-desktop-database}}. Finally, open GNOME Settings > Details > Default Applications and change Calendar.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.<br />
<br />
=== Wired networking ===<br />
<br />
This model does not have an Ethernet port, but it is possible to use a USB-to-Ethernet adapter. One such adapter is [http://www.asus.com/Tablet_Mobile_Accessories/USB_Ethernet_Cable/ ASUS USB Ethernet Cable], which works right out of the box.<br />
<br />
=== VGA output ===<br />
<br />
If you need to connect to an external monitor or projector through VGA, you can use an HDMI-to-VGA adapter such as [http://www.lindy-international.com/HDMI-to-VGA-Adapter.htm?websale8=ld0101.ld020102&pi=38191 this one], which works quite well.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=306353Lenovo IdeaPad U330p2014-03-21T19:41:21Z<p>Diogo: /* VGA output */</p>

Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners' guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />

<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.<br />
<br />
=== Wired networking ===<br />
<br />
This model does not have an Ethernet port, but it is possible to use a USB-to-Ethernet adapter. One such adapter is [http://www.asus.com/Tablet_Mobile_Accessories/USB_Ethernet_Cable/ ASUS USB Ethernet Cable], which works right out of the box.<br />
<br />
=== VGA output ===<br />
<br />
If you need to connect to an external monitor or projector through VGA, you can use an HDMI-to-VGA adapter such as [http://www.lindy.co.uk/audio-video-c2/converters-scalers-c105/video-c1511/hdmi-to-vga-converter-adapter-p6787 this one], which works quite well.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=306349Lenovo IdeaPad U330p2014-03-21T19:31:37Z<p>Diogo: /* Troubleshooting */</p>
<hr />
<div>[[Category:Lenovo]]<br />
<br />
== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners' guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disable KMS ===<br />
<br />
To avoid getting a blank screen during installation, you should disable KMS ([[Kernel mode setting]]). This can be done as follows: when booting from the USB stick, on the Arch Linux boot menu, press {{ic|e}} and then type {{ic|nomodeset}}. Finally, press enter to boot without KMS.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners' guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of at least 100MB (specify size: {{ic|100M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners' guide]].<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners' guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disable KMS ===<br />
<br />
To avoid getting a blank screen during installation, you should disable KMS ([[Kernel mode setting]]). This can be done as follows: when booting from the USB stick, on the Arch Linux boot menu, press {{ic|e}} and then type {{ic|nomodeset}}. Finally, press enter to boot without KMS.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners' guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of at least 100MB (specify size: {{ic|100M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners' guide]].<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners' guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
Useful GNOME extensions:<br />
<br />
* [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher]<br />
<br />
* [https://extensions.gnome.org/extension/584/taskbar/ TaskBar]<br />
<br />
* [https://extensions.gnome.org/extension/495/topicons/ TopIcons]<br />
<br />
How to show date next to the clock:<br />
<br />
* Run {{ic|dconf-editor}} and open org>gnome>desktop>interface. Select clock-show-date.<br />
<br />
How to make thunderbird the default calendar:<br />
<br />
* Edit {{ic|/usr/share/applications/thunderbird.desktop}} and append {{ic|text/calendar;text/x-vcard;}} to MimeType. Then run {{ic|sudo update-desktop-database}}. Finally, open GNOME Settings > Details > Default Applications and change Calendar.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=300981Lenovo IdeaPad U330p2014-02-23T19:23:27Z<p>Diogo: /* Disable KMS */</p>

=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of at least 100MB (specify size: {{ic|100M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
Useful GNOME extensions:<br />
<br />
* [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher]<br />
<br />
* [https://extensions.gnome.org/extension/584/taskbar/ TaskBar]<br />
<br />
* [https://extensions.gnome.org/extension/495/topicons/ TopIcons]<br />
<br />
How to show date next to the clock:<br />
<br />
* Run {{ic|dconf-editor}} and open org>gnome>desktop>interface. Select clock-show-date.<br />
<br />
How to make thunderbird the default calendar:<br />
<br />
* Edit {{ic|/usr/share/applications/thunderbird.desktop}} and append {{ic|text/calendar;text/x-vcard;}} to MimeType. Then run {{ic|sudo update-desktop-database}}. Finally, open GNOME Settings > Details > Default Applications and change Calendar.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=296368Lenovo IdeaPad U330p2014-02-06T11:00:39Z<p>Diogo: </p>

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of at least 100MB (specify size: {{ic|100M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
Useful GNOME extensions:<br />
<br />
* [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher]<br />
<br />
* [https://extensions.gnome.org/extension/584/taskbar/ TaskBar]<br />
<br />
* [https://extensions.gnome.org/extension/495/topicons/ TopIcons]<br />
<br />
How to show date next to the clock:<br />
<br />
* Run {{ic|dconf-editor}} and open org>gnome>desktop>interface. Select clock-show-date.<br />
<br />
How to make thunderbird the default calendar:<br />
<br />
* Edit {{ic|/usr/share/applications/thunderbird.desktop}} and append {{ic|text/calendar;text/x-vcard;}} to MimeType. Then run {{ic|sudo update-desktop-database}}. Finally, open GNOME Settings > Details > Default Applications and change Calendar.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=294362Lenovo IdeaPad U330p2014-01-25T17:00:40Z<p>Diogo: /* Troubleshooting */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
Useful GNOME extensions:<br />
<br />
* [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher]<br />
<br />
* [https://extensions.gnome.org/extension/584/taskbar/ TaskBar]<br />
<br />
* [https://extensions.gnome.org/extension/495/topicons/ TopIcons]<br />
<br />
How to show date next to the clock:<br />
<br />
* Run {{ic|dconf-editor}} and open org>gnome>desktop>interface. Select clock-show-date.<br />
<br />
How to make thunderbird the default calendar:<br />
<br />
* Edit {{ic|/usr/share/applications/thunderbird.desktop}} and append {{ic|text/calendar;text/x-vcard;}} to MimeType. Then run {{ic|sudo update-desktop-database}}. Finally, open GNOME Settings > Details > Default Applications and change Calendar.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292970Lenovo IdeaPad U330p2014-01-15T10:00:38Z<p>Diogo: /* Desktop environment */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
Useful GNOME extensions:<br />
<br />
* [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher]<br />
<br />
* [https://extensions.gnome.org/extension/584/taskbar/ TaskBar]<br />
<br />
* [https://extensions.gnome.org/extension/495/topicons/ TopIcons]<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292805Lenovo IdeaPad U330p2014-01-14T11:01:49Z<p>Diogo: /* Installation */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />

<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels, as described [[Advanced Linux Sound Architecture#Unmuting the channels|here]].<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
Useful GNOME extensions:<br />
<br />
* [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher]<br />
<br />
* [https://extensions.gnome.org/extension/584/taskbar/ TaskBar]<br />

* [https://extensions.gnome.org/extension/495/topicons/ TopIcons]<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292678Lenovo IdeaPad U330p2014-01-13T08:37:23Z<p>Diogo: </p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />

<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />

<br />
=== Screen brightness ===<br />
<br />
To be able to adjust screen brightness via the function keys, add the kernel parameter {{ic|acpi_osi&#61;Linux}}.<br />
<br />
The way to do this depends on the particular boot loader that you're using. See [[Kernel parameters]] for more info.<br />

<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
and then reboot.<br />
<br />
Install {{Pkg|alsa-utils}} and run {{ic|alsamixer}} to unmute the channels. Refer to [[Advanced Linux Sound Architecture#Unmuting the channels|Unmuting the channels]] for more info.<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Screen brightness ===<br />
<br />
To be able to adjust screen brightness via the function keys, add the kernel parameter {{ic|acpi_osi&#61;Linux}}.<br />
<br />
The way to do this depends on the particular boot loader that you're using. See [[Kernel parameters]] for more info.<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292573Lenovo IdeaPad U330p2014-01-12T15:27:24Z<p>Diogo: /* Sound card */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Sound card ===<br />
<br />
Set the default sound card by creating an {{ic|alsa-base.conf}} file in {{ic|/etc/modprobe.d/}}:<br />
<br />
{{hc|# nano /etc/modprobe.d/alsa-base.conf|options snd_hda_intel index&#61;1}}<br />
<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Screen brightness ===<br />
<br />
To be able to adjust screen brightness via the function keys, add the kernel parameter {{ic|acpi_osi&#61;Linux}}.<br />
<br />
The way to do this depends on the particular boot loader that you're using. See [[Kernel parameters]] for more info.<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to specify the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292570Lenovo IdeaPad U330p2014-01-12T15:20:09Z<p>Diogo: /* Installation */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />

* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Screen brightness ===<br />
<br />
To be able to adjust screen brightness via the function keys, add the kernel parameter {{ic|acpi_osi&#61;Linux}}.<br />
<br />
The way to do this depends on the particular boot loader that you're using. See [[Kernel parameters]] for more info.<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file to include the option {{ic|nohwcrypt&#61;1}}:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292285Lenovo IdeaPad U330p2014-01-10T22:58:55Z<p>Diogo: /* Network connectivity/latency */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />

The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Screen brightness ===<br />
<br />
To be able to adjust screen brightness via the function keys, add the kernel parameter {{ic|acpi_osi&#61;Linux}}.<br />
<br />
See [[Kernel parameters]] for more info on how to do this.<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file with the following content:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292282Lenovo IdeaPad U330p2014-01-10T22:53:42Z<p>Diogo: /* Screen brightness */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />
<br />

<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could or should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file with the following content:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292279Lenovo IdeaPad U330p2014-01-10T22:41:35Z<p>Diogo: /* Network connectivity/latency */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />
<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />

This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network connectivity/latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could/should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462 Wireless Network Adapter). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are some things that can be tried to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file with the following content:<br />
<br />
{{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}}<br />
<br />
and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292275Lenovo IdeaPad U330p2014-01-10T22:40:11Z<p>Diogo: /* Network latency */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />
<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />

If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could/should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462 Wireless Network Adapter). However, some testing with [[Wicd]] seems to indicate that the network adapter is working fine.<br />
<br />
There are at least two things that can be done to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create an {{ic|ath9k.conf}} file with the following content: {{hc|# sudo nano /etc/modprobe.d/ath9k.conf|options ath9k nohwcrypt&#61;1}} and then reboot.</div>Diogohttps://wiki.archlinux.org/index.php?title=Lenovo_IdeaPad_U330p&diff=292271Lenovo IdeaPad U330p2014-01-10T22:38:57Z<p>Diogo: /* Network latency */</p>

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />
<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />

== Overview ==<br />
<br />
There are no major issues with Lenovo U330p. Everything works.<br />
<br />
This page contains just some comments that may be useful during installation or troubleshooting.<br />
<br />
== Hardware ==<br />
<br />
The unit used for testing contained the following hardware:<br />
<br />
* Intel Core i5-4200U Processor<br />
<br />
* Intel HD Graphics 4400<br />
<br />
* Atheros AR9462 Wireless Network Adapter<br />
<br />
* A thin Seagate 500GB hybrid drive (i.e. 500GB HDD + 8GB SSD).<br />
<br />
=== Replacing the hard drive ===<br />
<br />
'''Warning:''' this section is intended for documentation purposes only, and is not necessary to perform at all. Please be advised against opening the computer by yourself and performing operations that could damage the machine, besides making the warranty void.<br />
<br />
The hard drive of this unit was replaced by a Samsung 840 EVO 250GB SSD. Other 2.5-inch SATA-3 SSDs may be used instead, as long as they are not too thick.<br />
<br />
For this purpose:<br />
<br />
* Power off and disconnect all cables.<br />
<br />
* Remove the 10 screws from the back cover of the machine.<br />
<br />
* In addition, remove the 2 screws where the back cover folds over to the other side. See Figure 1 on page 34 of the [http://download.lenovo.com/consumer/mobiles_pub/ideapad_u330pu330touchu430pu430touch_hmm.pdf Hardware Maintenance Manual] for this machine.<br />
<br />
* Double-check that all screws have been removed (12 in total).<br />
<br />
* Pull the back cover gently, until the two plastic latches inside it are released.<br />
<br />
* Unscrew the hard drive, but before pulling it out move away some very thin wires that may be placed over it. Do this very gently and carefully.<br />
<br />
* Insert the new drive and screw it, while rearranging the thin wires very gently.<br />
<br />
* Put the cover back on, and press a little bit so that the plastic latches will lock themselves into place.<br />
<br />
* Then put back the 12 screws. Use sufficient, but not too much torque.<br />

<br />
== Installation ==<br />
<br />
The best way to ensure that Arch Linux is correctly installed is to follow the [[Beginners Guide]] step by step.<br />
<br />
=== Preparing the installation medium ===<br />
<br />
Use another machine to download the latest image from the [https://archlinux.org/download/ Download] page and burn the ISO image into a USB stick by following the instructions in [[USB Installation Media]].<br />
<br />
=== BIOS setup ===<br />
<br />
Before booting with the USB stick, enter the BIOS in order to prepare the machine for the new OS. For that purpose, press the small button on the side panel next to the HDMI port. A boot menu will appear. Select "BIOS Setup", and then:<br />
<br />
* In the "Security" menu, disable "Secure Boot" (although Arch Linux can be configured to work with secure boot, this will probably spare you a few issues during installation).<br />
<br />
* In the "Boot" menu, leave "Boot Mode" set to "UEFI", and "USB Boot" enabled.<br />
<br />
* In the "Exit" menu, set "OS Optimized Defaults" to "Other OS". Exit by saving changes.<br />
<br />
=== Disk partitions ===<br />
<br />
Use {{ic|cgdisk}} to create the disk partitions, as explained in the [[Beginners Guide]].<br />
<br />
If the machine will be running Arch Linux only, then:<br />
<br />
* Create a first partition of 512MB (specify size: {{ic|512M}}) for UEFI. The partition should be of type {{ic|ef00}}.<br />
<br />
* Create a second partition that takes up all of the remaining disk space. The partition should be of type {{ic|8300}}.<br />
<br />
* There is no need for a separate swap partition. Instead, create a swap file as explained in [[Swap]].<br />
<br />
Format the partitions as explained in the [[Beginners Guide]].<br />
<br />
=== Bootloader ===<br />
<br />
Towards the end of the [[Beginners Guide]] you will install and configure a bootloader<br />
<br />
If the machine will be running Arch Linux only, then gummiboot is simple and works nicely.<br />
<br />
=== Video driver ===<br />
<br />
Use {{Pkg|xf86-video-intel}}. This is the correct driver for the hardware and it is being developed [https://01.org/linuxgraphics/community/xf86-video-intel with the support of Intel].<br />
<br />
At the time of this writing (Dec. 2013), Intel has just released [https://01.org/linuxgraphics/documentation/2013-intel-core-processor-family extensive information] about this graphics hardware.<br />
<br />
=== Touchpad ===<br />
<br />
Install {{Pkg|xf86-input-synaptics}} as explained in the [[Beginners Guide]].<br />
<br />
This will make sure that the touchpad works correctly and will also provide two-finger scrolling.<br />
<br />
=== Desktop environment ===<br />
<br />
Despite general criticism, GNOME 3 is an excellent choice. It can be installed smoothly (see [[GNOME]]) and provides a very productive work environment.<br />
<br />
For example, the Windows key takes you to the dashboard, where you can type to search for applications and use scrolling to move across workspaces. You can also tile windows on the screen easily, either by moving them to an edge of the screen or by using a combination of the Windows key with an arrow key.<br />
<br />
== Troubleshooting ==<br />
<br />
=== Use of headphones ===<br />
<br />
If you use headphones often and you shutdown the machine with the headphones plugged in, it may happen that in the next reboots the sound is directed to the headphones by default, even when the headphones are not plugged in.<br />
<br />
To fix this issue:<br />
<br />
* Plug the headphones in and out. The sound should now be directed to the speakers.<br />
<br />
* Install and run {{Pkg|pavucontrol}} once (you don't have to do anything, just open it, browse through the different tabs, and close it).<br />
<br />
* Reboot the machine (ensuring that the headphones are not plugged in). The sound should now be directed back to the speakers by default.<br />
<br />
=== HDMI sound output ===<br />
<br />
If you are connecting to an external TV through an HDMI cable and the TV gets image but no sound, you need to switch the audio output from the Analog to the HDMI sound sink.<br />
<br />
If you're using GNOME 3, this can be done easily with a shell extension such as [https://extensions.gnome.org/extension/751/audio-output-switcher/ Audio Output Switcher].<br />
<br />
=== Connecting an iPhone or iPad ===<br />
<br />
There seem to be some problems in pairing with these devices.<br />
<br />
However, if the only thing you need is to import photos from the device, you can do this with {{Pkg|shotwell}} as follows:<br />
<br />
* Connect the mobile device to a USB port using the charging cable.<br />
<br />
* When the prompt appears on the mobile device, select "Trust this computer".<br />
<br />
* Open Shotwell and by clicking on the left pane on "iPhone" (or "iPad") you will be able to import the photos.<br />
<br />
=== Battery life ===<br />
<br />
Battery life is quite long (6 to 9 hours) without the need for any special power management software. (Note: the fact that this unit had the HDD replaced by an SSD may have contributed to extend its battery life.)<br />
<br />
=== Network latency ===<br />
<br />
When using [[NetworkManager]], it appears that wireless networking is not as responsive as it could/should be. For example, there is a noticeable lag when trying to acess some websites that should open immediately (e.g. Google, YouTube, etc.)<br />
<br />
On the Web, there are several reports of connectivity/latency problems with this particular hardware (Atheros AR9462 Wireless Network Adapter). However, some testing with [[Wicd]] suggests that the network adapter is working fine.<br />
<br />
There are at least two things that can be done to alleviate this problem:<br />
<br />
* Disable IPv6 in NetworkManager. Go to Wi-Fi settings and turn off IPv6 for each wireless network that you connect to.<br />
<br />
* Create <br />
