== Input/touchpad ==
Before running the Arch installer, you MUST install and configure a GPT partition scheme. If you do not, you will get '''terrible''' performance when writing small files (which should effect most users).
+
  
==(Pre-install) Configuring GPT (Erasing the whole disk)==
+
The keyboard and touchpad work more or less without problems using the {{Pkg|xf86-input-keyboard}} and {{Pkg|xf86-input-synaptics}} modules, respectively. Right- and left-clicking works, as well as Two-Finger scroll. Tapping is enabled out of the box and can be disabled in {{bc| /etc/X/xorg.conf.d/10-synaptics.}}
You must install some tools that are not included in the installer (you do not have to update pacman):
+
<pre>$ dhcpcd eth0</pre>
+
Update `pacman` and install `gdisk`
+
<pre>$ pacman -Syy </pre>
+
<pre>$ pacman -S gdisk</pre>
+
Launch `gdisk`
+
<pre>$ gdisk /dev/sda</pre>
+
  
Since you want to start a new GPT table, choose the option to create a new GPT table.
+
== Bluetooth ==
The partitioning scheme here is important(!). Since you have to use GRUB2 to boot from a GPT disk, you MUST create a 200MB blank partition that you will never touch again(!). This small partition will hold GRUB2's core.img used for booting.
+
  
 +
Installing a tool like "blueman" from the AUR and starting the bluetooth DAEMON allowed communication to bluetooth keyboards and mice.
 +
Bluetooth speakers not tested. (*users feel free to add to this)
  
Using `gdisk`, press `n` to create a new partition, keeping an eye that the start sector should be '''2048''' and for end sector, enter `+200M`. Do not change the partition type; it should default to 8300. '''Remember to not format this in the installer'''.
+
== Nvidia GPU (Optimus) ==
  
 +
{{Tip|Your best bet for this part is to install {{AUR|yaourt}} from the AUR to ease in installing the following packages}}
  
From here, you can create the rest of your partitions. We will use `parted` to make your drive bootable later. Don't forget to write the changes to disk using the `w` command in `gdisk`.
+
You need to install the packages {{Pkg|bumblebee}} and {{Pkg|bbswitch}}.
 
+
 
+
Here you should '''reboot'''. After you boot back into the installer ISO, reinstall `gdisk`.
+
 
+
 
+
Now we need to create an MBR for the GPT disk . This allows GRUB2 to be installed to disk.
+
 
+
 
+
Open `gdisk` and press `r`, then press `h`... A common looking process is below:

What you just did, was create a Hybrid MBR. You should read more about this if you want to understand it.
+
 
+
 
+
At this point, you should '''reboot''' again so the kernel is aware of the disk changes.
+
 
+
 
+
You do not need to reinstall `gdisk` at this point.
+
 
+
 
+
''' At this point, you should install archlinux with the installer. '''
+
 
+
 
+
==(Arch Installer) Installing==
+
*Assure that you do not install/configure anything on the first 200MB partition that you created. You should start modifying and configuring partitions starting after that partition; usually /dev/sda2
+
 
+
*Do '''NOT''' install GRUB or any bootloader via the installer.
+
 
+
 
+
==(Post-install) Installing GRUB2==
+
*CHROOT into your new installation
+
 
+
After you have exited the installer, mount the required data in order to use your new installation:
+
<pre>$ mount -o bind /dev /mnt/dev</pre>
+
<pre>$ mount -t proc /proc /mnt/proc</pre>
+
<pre>$ mount -t sysfs /sys /mnt/sys</pre>
+
 
+
Now enter the chroot.
+
<pre>$ chroot /mnt bash</pre>
+
 
+
You are now in your new installation.
+
From here, update pacman and install 'gdisk', 'parted', and 'grub2-bios'.
+
 
+
 
+
We need to do a few things here. We need change a '''bios_grub FLAG''' on that 200M partition, and we need to add a '''boot FLAG''' on the partition with your /boot partition.
+
 
+
<pre>$ parted /dev/sda</pre>
+
<pre>$(parted) set 1 bios_grub on</pre>
+
<pre>$(parted) set 2 boot on</pre>
+
 
+
 
+
Now Install GRUB2
+
<pre>$ grub-install --directory=/usr/lib/grub/i386-pc --target=i386-pc --boot-directory=/boot --recheck --debug /dev/sda</pre>
+

Follow the rest of the Sections below to get all of the hardware working.

=Nvidia GPU (Optimus)=
+
{{Note|Your best bet for this part is to install 'yaourt' from the AUR to ease in installing the following packages}}
+
Read the [https://wiki.archlinux.org/index.php/Bumblebee Bumblebee]/optimus page. I will only outline a few things...
+
 
+
You need to install the packages (and all of their dependencies) :
+
*bumblebee
+
*nvidia-bumblebee
+
*nvidia-utils-bumblebee
+
*bbswitch
+
 
+
  
 
In short, Bumblebee allows you to use the switchable GPU and use it only when you want to via the 'optirun' application.

Be sure to add 'bumblebeed' to your DAEMONS array in '''rc.conf'''.
+
Be sure enable '''bumblebeed''' [[Systemd]] service to start Bumblebee at boot.
  
 
Once you reboot, you should start seeing huge power saving.

=Sound=
+
Read the [[Bumblebee]] page for further informations.
Install the typical ALSA packages (libs, oss, plugins, utils).
+
After the installation, you need to launch alsamixer
+
<pre>$ alsamixer</pre>
+
  
And raise the '''SPEAKER''' level, pressing '''ESC''' to save. You should now have (low quality) sound. This is a work in progress.
+
== Suspend/hibernate ==
  
=Suspend / Hibernate=
+
The USB unbind hook is no longer necessary as of [http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=dbf0e4c7257f8d684ec1a3c919853464293de66e Linux 3.5].
Attempting to suspend will put your machine into a coma. The issue here is that you need to unload the EHCI module before sleeping.
+
{{ Note| ACPI by default doesn't call pm-suspend, if we want to customize the sleep process, we need pm-suspend }}
+
  
Create a script:
+
{{Note|ACPI by default doesn't call pm-suspend, if we want to customize the sleep process, we need pm-suspend }}
<pre>$ nano /etc/pm/sleep.d/20-asus-u31sd</pre>
+
  
<pre>
+
If you want sleep your machine when you '''close your lid''', you need to edit ACPI handler script {{ic|/etc/acpi/handler.sh}}
#!/bin/sh
+
  
BUSES="0000:00:1a.0 0000:00:1d.0"
+
Change line 20, to this:
 +
SLPB|SBTN)    pm-suspend ;;
  
case "${1}" in
+
And Towards the bottom, make lines 58 and 59 look line like this:
    hibernate|suspend)
+
{{bc|close)
    # Switch USB buses off
+
         pm-suspend
    for bus in $BUSES; do
+
}}
         echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/unbind
+
    done
+
    ;;
+
    resume|thaw)
+
    # Switch USB buses back on
+
    for bus in $BUSES; do
+
        echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/bind
+
    done
+
    ;;
+
esac
+
</prev
+
  
Give it executable flag:
+
So now you can use the hotkey ({{Keypress|F1}}) or close your lid and your laptop will sleep.
<pre>$ chmod +x /etc/pm/sleep.d/20-asus-u31sd</pre>
+
  
 +
== Fn multimedia keys ==
  
 +
As with most Asus laptops/netbooks, this laptop sends its Multimedia events via ACPI. Using '''acpi_listen''', I was able to discover the button commands the buttons sent to acpi. Add the following to your {{ic|/etc/acpi/handler.sh}} file (make sure you add this after the ;; in the button/lid section):
 +
{{bc|
 +
    button/volumeup)
 +
      amixer set Master 5+
 +
      ;;
 +
    button/volumedown)
 +
      amixer set Master 5-
 +
      ;;
 +
    button/mute)
 +
      amixer set Master toggle
 +
      ;;
 +
}}
  
If you want sleep your machine when you'''close your lid''', you need to edit ACPI handler script:
+
You can mess with these values to move your volume at different intervals, 5 seemed to work well for me.
 
+
<pre>$ nano /etc/acpi/handler.sh</pre>
+
 
+
Change line 20, to this:
+
<pre> SLPB|SBTN)    pm-suspend ;;</pre>

== Optimize power consumption ==
  
So now you can use the '''hotkey (F1)''' or close your lid and your laptop will sleep.

Note: This page was written for the i3 model but I'm sure the i5 model will not be much different

What does not work out of the box

  • Sleep/Hibernate (see below)
  • Nvidia GPU (Switchable GPU, see below)
  • Fn Volume Keys (see below)

What works out of the box / with default configuration

  • CPU (all cores detected)
  • Wireless
  • Ethernet
  • Framebuffer resolution (nouveau and intel xorg drivers provide this)
  • Intel GPU
  • Touchpad
  • Bluetooth
  • Hotkeys (Brightness / Monitor on-off / wifi / sleep)
  • USB

Not tested

  • HDMI

Input/touchpad

The keyboard and touchpad work more or less without problems using the xf86-input-keyboard and xf86-input-synaptics modules, respectively. Right- and left-clicking works, as well as Two-Finger scroll. Tapping is enabled out of the box and can be disabled in
 /etc/X/xorg.conf.d/10-synaptics.

Bluetooth

Installing a tool like "blueman" from the AUR and starting the bluetooth DAEMON allowed communication to bluetooth keyboards and mice. Bluetooth speakers not tested. (*users feel free to add to this)

Nvidia GPU (Optimus)

Tip: Your best bet for this part is to install yaourtAUR from the AUR to ease in installing the following packages

You need to install the packages bumblebee and bbswitch.

In short, Bumblebee allows you to use the switchable GPU and use it only when you want to via the 'optirun' application.

Be sure enable bumblebeed Systemd service to start Bumblebee at boot.

Once you reboot, you should start seeing huge power saving.

To check and make sure that you aren't using your GPU all the time:

$ lsmod | grep nv

Should return nothing, this means your GPU is off.

You can check your GPU by running glxgears with and without the 'optirun' prefix and comparing the Frames Per Second.

Read the Bumblebee page for further informations.

Suspend/hibernate

The USB unbind hook is no longer necessary as of Linux 3.5.

Note: ACPI by default doesn't call pm-suspend, if we want to customize the sleep process, we need pm-suspend

If you want sleep your machine when you close your lid, you need to edit ACPI handler script /etc/acpi/handler.sh

Change line 20, to this:

SLPB|SBTN)    pm-suspend ;;

And Towards the bottom, make lines 58 and 59 look line like this:

close)
        pm-suspend

So now you can use the hotkey (Template:Keypress) or close your lid and your laptop will sleep.

Fn multimedia keys

As with most Asus laptops/netbooks, this laptop sends its Multimedia events via ACPI. Using acpi_listen, I was able to discover the button commands the buttons sent to acpi. Add the following to your /etc/acpi/handler.sh file (make sure you add this after the ;; in the button/lid section):

    button/volumeup)
      amixer set Master 5+
      ;;
    button/volumedown)
      amixer set Master 5-
      ;;
    button/mute)
      amixer set Master toggle
      ;;

You can mess with these values to move your volume at different intervals, 5 seemed to work well for me.

Optimize power consumption

Add this to the kernel line of your bootloader[1]:

pcie_aspm=force i915.i915_enable_rc6=1
