This page contains instructions, tips, pointers, and links for installing and configuring Arch Linux on the ASUS EEE 901 PC.
 
 
 
Most of the article can also be applied to eeepc-models which are similar to the 901 such the 901H, 1000 and 1000H. If you discover a configuration or software option applicable to a certain model that differs from what is described in this article, please add it, with a note about which model the suggestion pertains to.
 
 
 
== Install tips for the Asus Eee PC ==
 
 
 
This wiki page supplements these pages: '''[[Beginners Guide]]''', the '''[[Official Arch Linux Install Guide|Official Install Guide]]''', and '''[[Installing Arch Linux on the Asus EEE PC]]'''. Please refer to those guides ''first'' before following the eeepc-specific pointers on this page.
 
 
 
Most of this information is from the Arch Forum EEE 901 [https://bbs.archlinux.org/viewtopic.php?id=53464 thread]. Consult this thread, and other resources on the Arch forum, for more details and discussion.
 
 
 
== Kernel installation and configuration ==
 
 
 
Follow the Arch Linux installation Guide to install the latest stock distribution from USB media or CDROM. Install the '''BASE''' and '''DEVEL''' package categories. Reboot your PC.
 
 
 
As of the advent of kernel 2.6.30, all drivers needed for the EEE 901 are included in the Arch Linux stock kernel. In case you would like to compile your own kernel, make sure that you build the following modules:
 
 
 
Network card:
 
Device Drivers - Ethernet (1000Mbit) - Atheros L1E Gigabit Ethernet support
 
WiFi card:
 
Device Drivers - Staging Drivers - Ralink 2860
 
Eee Hotkey stuff:
 
Device Drivers - X86 Platform Specific Device Drivers - EeePC Hotkey Driver
 
Video Camera:
 
Device Drivers - Multimedia Devices - Video Capture adapters - V4L USB devices - USB Video Class (UVC)
 
Sound Card:
 
Device Drivers - Sound card support - ALSA - PCI Sound devices - Intel HDA - Build Realtek HDA codec
 
Touchpad:
 
Device Drivers - Input Device support - Mice - PS/2 mouse - Synaptics & Elantech PS/2 protocol ext.
 
 
 
For flawless operation with the eee-control FSB frequency changing mechanism, you have to compile
 
Device Drivers - I2C support - I2C Hardware Bus support - Intel 82801 (ICH)
 
as a '''module'''.
 
 
 
For more general information about building custom Arch Linux kernels, see [[Kernel Compilation]].
 
 
 
== OS configuration ==
 
 
 
To support the devices listed below, make sure the module {{ic|eeepc_laptop}} is loaded on boot using {{ic|modules.d}} directory:
 
{{hc|/etc/modules-load.d/eeepc_laptop|
 
eeepc_laptop
 
}}
 
 
 
=== Networking: ethernet ===
 
 
 
Ethernet (wired) network access should work right out of the box with precompiled kernels, or with '''atl1e''' module you built from AUR.
 
 
 
=== Networking: wireless ===
 
 
 
From Kernel 3.0, The staging driver rt2860sta is replaced by mainline driver rt2800pci. See [[Wireless Setup#rt2860 and rt2870]].
 
 
 
After a bios-upgrade the wireless-card of the Eee PC will be disabled by default, so if you have any troubles with wlan check that it is enabled in the bios.
 
 
 
# enable
 
echo 1 > /sys/devices/platform/eeepc/rfkill/rfkill0/state
 
# disable
 
echo 0 > /sys/devices/platform/eeepc/rfkill/rfkill0/state
 
 
 
Here's a working example wpa_supplicant config file:
 
 
 
ctrl_interface=/var/run/wpa_supplicant
 
# change ap_scan to 2 if running into problems
 
ap_scan=1
 
fast_reauth=1
 
eapol_version=1
 
 
network={
 
  key_mgmt=NONE
 
}
 
 
network={
 
  ssid="WPA"
 
  scan_ssid=1
 
  proto=WPA
 
  key_mgmt=WPA-PSK
 
  pairwise=TKIP
 
  group=TKIP
 
  #psk="passphrase"
 
  psk=hexkey
 
}
 
 
network={
 
  ssid="WEP"
 
  scan_ssid=1
 
  key_mgmt=NONE
 
  #wep_key0="passphrase"
 
  wep_key0=hexkey
 
  wep_tx_keyidx=0
 
}
 
 
 
Your mileage may vary, but experience seems to show that the {{ic|ap_scan=1}} parameter is critical.  Try tweaking the other "header" settings, too, if you continue to experience problems.
 
 
 
=== ACPI (hotkeys) ===
 
 
 
==== Option 1: acpi-eeepc-generic ====
 
 
 
Install {{AUR|acpi-eeepc-generic}}.
 
For this package to work, make sure the '''eeepc_laptop''' and '''rfkill''' modules are loaded at boot.
 
 
 
Consult the notes included with the install for instructions on configuring {{ic|/etc/conf.d/acpi-eeepc-generic.conf}}.
 
 
 
This will enable all the {{ic|Fn + xx}} keys and the four silver hotkey buttons buttons as configured in the default Xandros distribution, with some minor variations. Edit the {{ic|/etc/conf.d/acpi-eeepc-generic.conf}} file to change or modify the behavior of the function keys.
 
 
 
==== Option 2: configure the stock kernel ACPI features ====
 
 
 
Enable the ASUS_LAPTOP (''Device Drivers > Misc Devices'') switch in your kernel config and turn off ACPI_ASUS switch (''Power managment options > ACPI'').
 
 
 
To enable the FN keys, the WLAN and Camera on/off toggles, etc., activate the EEEPC_LAPTOP switch also (''Device Drivers > Misc Devices'').
 
 
 
You can use Robertek's PKGBUILD and files for '''acpi-www901''' at http://robertek.brevnov.net/files/linux/arch/acpi-eee901/ as a base to incorporate the stock kernel modules and ASUS OSD into the ACPI system.
 
 
 
Note: The kernel interfaces {{ic|/proc/acpi/asus}} or {{ic|/proc/acpi/eee}} are not available with the '''eeepc_laptop''' module. The corresponding '''eeepc_laptop''' interfaces are files in: {{ic|/sys/devices/platform/eeepc/}}. You may need to edit some of the scripts under {{ic|/etc/acpi/}} to point to the correct paths.
 
Also easier links to the interfaces can be found inside of /sys/class/ . For instance the first battery is in /sys/class/power_supply/BAT0/ .
 
 
 
==== ASUS OSD ====
 
 
 
Asus OSD is included as part of the '''acpi-eee901''' package. Simply add the command {{ic|asusosd &}} to your desktop manager startup script, or create the file {{ic|/etc/xdg/autostart/asusosd.desktop}} with these contents:
 
 
 
[Desktop Entry]
 
Encoding=UTF-8
 
Name=ASUS OSD
 
Comment=ASUS OSD
 
Exec=/usr/bin/asusosd
 
Terminal=false
 
Type=Application
 
StartupNotify=false
 
Hidden=false
 
 
 
=== Bluetooth ===
 
 
 
Currently, Bluetooth is not enabled with the {{ic|Fn+F2}} hotkey. To communicate with Bluetooth devices, make sure Bluetooth has been enabled in the BIOS.
 
 
 
To enable/disable bluetooth from the command line :
 
 
 
  # enable
 
  echo 1 > /sys/devices/platform/eeepc/bt
 
  # disable
 
  echo 0 > /sys/devices/platform/eeepc/bt
 
 
 
Install the {{Pkg|bluez}} package.  Make sure the '''bluetooth''' module is loaded.
 
 
 
See the Arch Linux [[Bluetooth]] and [[Bluetooth Mouse]] wiki pages for more information about configuring and using Bluetooth devices.
 
 
 
=== Webcam ===
 
 
 
To enable/disable the camera:
 
 
 
# enable
 
echo 1 > /sys/devices/platform/eeepc/camera
 
# disable
 
echo 0 > /sys/devices/platform/eeepc/camera
 
 
 
To record video and take photos, you may use {{Pkg|cheese}} or the {{Pkg|wxcam}} package.
 
 
 
To simply test the camera, you may use {{ic|mplayer}}:
 
 
 
mplayer -fps 15 tv://
 
 
 
The webcam is reported to work with Skype.
 
 
 
=== Audio ===
 
 
 
Audio output is enabled with the default ALSA drivers distributed with the kernels. You may need to install the '''alsa-lib''' and '''alsa-utils''' packages to get full functionality.
 
Make sure the '''snd-hda-intel''' module is loaded.
 
 
 
Both the microphone and PC speakers should work out-of-the-box with current versions of the kernel and ALSA drivers. A common gotcha: if you're not getting any sound, did you run {{ic|alsamixer}} and unmute your channels?
 
 
 
See the Arch Linux [[ALSA]] wiki page for more information about configuring and using ALSA.
 
 
 
=== X ===
 
 
 
{{Out of date|This section is out-of-date, and needs to be cleaned up.}}
 
 
 
==== Video ====
 
 
 
You will need the {{Pkg|xf86-video-intel}} video driver.
 
 
 
To set-up the touchpad, (including two-fingers scrolling & tapping), just install {{Pkg|xf86-input-synaptics}} (no xorg.conf required).
 
 
 
Some users have reported problems with vsync and the '''xf86-video-intel''' driver. These problems may be partially solved in the application (see this forum [https://bbs.archlinux.org/viewtopic.php?pid=416645#p416645 post].)
 
 
 
===== Connecting an external monitor =====
 
 
 
The xrandr utility (part of Xorg) can be used to switch into screen modes appropriate either for the EeePC's LCD or an externally connected monitor. Running {{ic|xrandr -q}} will show you the available output devices and the supported modes. Then run the tool as follows:
 
 
 
xrandr --output LVDS --off  --output VGA --auto  # disable LCD, enable monitor
 
xrandr --output LVDS --auto --output VGA --auto  # enable both
 
etc.
 
 
 
Your monitor will probably support a bigger resolution than the LCD. To make use of that additional screen space, tell the X server to create an appropriately large framebuffer by adding the "Virtual" directive to the Screen/Display section in {{ic|/etc/X11/xorg.conf}}:
 
 
 
Section "Screen"
 
  Identifier "Screen0"
 
  Device    "Card0"
 
  Monitor    "Monitor0"
 
  DefaultDepth    24
 
  SubSection "Display"
 
      Viewport  0 0
 
      Depth    24
 
      Virtual 1600 1200  # max resolution is 1600x1200
 
  EndSubSection
 
EndSection
 
 
 
On the LCD, the additional space will be unused, but when switching to the external monitor, the screen will be. Note that some window managers (such as ratpoison) might need to be restarted to realize that the visible screen size has changed.
 
 
 
===== Letterboxing with XRandR =====
 
 
 
If you have set up your X server and kernel to use KMS you might have some trouble getting a 800x600 resolution letterboxed (centered) rather than stretched, which might be unpleasant in some programs that do not support 1024x600 such as older games. This is because with KMS the xrandr syntax is a bit different [https://bugs.freedesktop.org/show_bug.cgi?id=24331].
 
To get a centered 800x600 visual field on your 1024x600 panel run:
 
$ xrandr --output LVDS1 --set "scaling mode" "Center"
 
$ xrandr -s 800x600
 
Replace "800x600" with "1024x600" to go back to the native resolution.
 
 
 
==== Mouse and Synaptics driver ====
 
 
 
To enable the Synaptics drivers, first install the {{Pkg|xf86-input-synaptics}} package.
 
 
 
You also need the {{Pkg|xf86-input-evdev}} driver for Xorg.
 
 
 
Then make these changes to {{ic|/etc/X11/xorg.conf}}:
 
 
 
Section "ServerLayout"
 
  Identifier    "ArchLinux"
 
  Screen      0  "Screen0"

The latest version of the Elantech touchpad driver patch is available at http://arjan.opmeer.net/elantech/ or here [http://www.mac-how.net/ mac how to] You'll need to apply this patch to your kernel source, then recompile the kernel.  This patch has been tested on the 2.6.27.6 and 2.6.27.7 kernels.
 
 
 
==== Miscellaneous ====
 
 
 
If you do not have an {{ic|xorg.conf}} file, and want to configure the keyboard layout on the fly:
 
 
 
# Set keyboard to cz with qwerty
 
setxkbmap cz qwerty
 
 
 
To configure the mouse speed:
 
# Set mouse movement and acceleration (you need to tweak this to your needs)
 
xset m 2 1
 
 
 
== Performance tips ==
 
 
 
The following tweaks can be used to improve performance and/or power consumption.
 
 
 
=== Speedstep ===
 
 
 
Speedstep is included by default in the Linux 2.6.x kernel.
 
 
 
The '''zen-eee901''' kernels contain the Speedstep modules. Create a proper module file in {{ic|/etc/module.d}} to load {{ic|acpi-cpufreq}} at boot:
 
{{hc|/etc/module.d/acpi-cpufreq.conf|
 
acpi-cpufreq
 
}}
 
 
 
See [http://rffr.de/acpi here] for more information.
 
 
 
For more information on overclocking the Asus EEE PC line, see http://wiki.eeeuser.com/howto:overclockfsb
 
 
 
{{Note|Speedstep is applicable to the 901 as it's CPU is of the Intel Atom family. The eee 900 and 904 use an Intel Celeron M CPU and so should use the p4-clockmod module instead. }}
 
 
 
=== Boot Booster ===
 
 
 
Enable Asus Boot Booster feature in BIOS to skip some tests during boot.
