Installing Arch

This wiki page supplements these pages: Beginners Guide, the 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.

Following the Beginners Guide

Graphics, Ethernet, Wireless, Audio and the Card Reader work "out of the box".

Camera

Is working fine with Ekiga, Skype displays the image upside-down
to fix this use command:

for x86_x64

LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype

for i686

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

To make this happen automatically just create a script named skyp (or anything you want it to be)

#!/bin/bash

#get the architecture of the system
arch=`uname -m`

#corrects upside down webcam in skype
case $arch in
     x86_64)
       LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype;
       ;;
     i686)
       LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype;
       ;;
esac

Save this script as "skyp" and '#chmod +x skyp'. Move this script to '/usr/bin/' with '#mv skyp /usr/bin/'. From now on typing in skyp should load skype with the proper webcam orientation.

Function Keys

Suspend-, Brightness- and Audiokeys work. Others may need special configuration. My Suspendkey was executing the suspend from KDE and from the acpi Interface. I disabled the KDE event, and now Suspend works.

In openbox, editting ~/.config/rc.xml and appending (under <keyboard>); this was taken from https://wiki.archlinux.org/index.php/Openbox:

   <!-- Keybindings for audio control -->
   <keybind key="XF86AudioRaiseVolume">
     <action name="Execute">
       <command>amixer set Master 5%+ unmute</command>
     </action>
   </keybind>
   <keybind key="XF86AudioLowerVolume">
     <action name="Execute">
       <command>amixer set Master 5%- unmute</command>
     </action>
   </keybind>
   <keybind key="XF86AudioMute">
     <action name="Execute">
       <command>amixer set Master toggle</command>
     </action>
   </keybind>

will make the audio keys work if alsa is installed.

Installing OpenBox

OpenBox can be installed by issuing #pacman -S openbox. Follow the instructions on screen to copy the openbox scripts to '~/.config/openbox/'.

Rotating the touch screen in openbox

Editing the openbox rc.xml file in '~/.config/openbox/rc.xml' will allow configuration of the Express Gate button. Open a terminal and run $xev (non-root) to find out the key associated with the Express Gate button (just click it while in xev). For my system it was key 248 (0xF8) in hexadecimal. Edit your ~/.config/openbox/rc.xml to include the following code under <keyboard>:

   <!-- Keybindings for express gate button --> 
   <keybind key="0xF8">
       <action name="ShowMenu">
         <menu>root-menu</menu>
        </action>
    </keybind>

This will bind the express gate key to show the openbox menu whenever clicked.

To rotate the screen, use the following script (note the following script can also be bound to the expressgate button itself to generate rotations (bypass any menu):

#!/bin/bash

echo "

#                     written by Mark Lee                    #

# Check if touch_rotate is set up in /usr/bin

    		echo 3 >cur_rot;
    		exit;
    		;;
	esac

Edit '~/.config/openbox/menu.xml' to include the following code:

		<menu id="root-menu-773645" label="Rotate Screen">
			<item label="Normal">
				<action name="Execute">
					<execute>
						touch_rotate normal
					</execute>
				</action>
			</item>
			<item label="Right">
				<action name="Execute">
					<execute>
						touch_rotate right
					</execute>
				</action>
			</item>
			<item label="Upside Down">
				<action name="Execute">
					<execute>
						touch_rotate upside-down
					</execute>
				</action>
			</item>
			<item label="Left">
				<action name="Execute">
					<execute>
						touch_rotate left
					</execute>
				</action>
			</item>

You can edit the position of this piece of code (if you know XML) or just add it in somewhere before the last line '</openbox_menu>' of the script. Change the position by using obmenu (GUI interface for editing openbox menu).

On Screen Keyboard

Install kvkbd with from the Arch user repository (if using packer : packer -S kvkbd). Make sure you have some sort of system tray (I used tint2) and edit '~/.config/openbox/autostart' to include the following statement:

kvkbd &

This will start up kvkbd everytime openbox starts up. Once kvkbd is started up it will appear in the system tray, simply clicking the icon in the tray will pop out the virtual keyboard.

Suspend2RAM

Touchscreen is not working afterwards.

It will work after you reload hid_multitouch kernel module:

# rmmod hid_multitouch
# modprobe hid_multitouch

As a workaround, you can add the following line to the file '/etc/pm/config.d/modules':

SUSPEND_MODULES="hid_multitouch"

This way the kernel module will be explicitly unloaded before suspend.

If you are using twofing you also need to restart it:

$ killall twofing
$ twofing --wait

This instruction may be useful for solving this problem

Hibernate

Not Working.

Multi-Touch

Modern kernels out-of-the-box support multitouch in our devises, but not Xorg. In Ubuntu there is some Xorg patches for a multitouch support and utouch (ginn) for multitouch gestures, but in other linux distributives you can use twofing. You can find utouch packages in AUR, but they are untested on our device.

But you can use twofing experimental daemon to use some gestures.

While we are waiting someone to build AUR packages, we can install it from sources. Get the latest git version here.

After this, you must fix /etc/udev/rules.d/70-touchscreen-egalax.rules file. Replace custom touchscreen code rule to following:

SUBSYSTEMS=="usb",ACTION=="add",KERNEL=="event*",ATTRS{idProduct}=="0186",SYMLINK+="twofingtouch",RUN+="/bin/chmod a+r /dev/twofingtouch"

Replace idProduct variable to idProduct of latest model touchscreen ID. To to check it, try this

lsusb | grep "ASUS Comp"

Then, create symlink to touchscreen device:

ln -s /dev/input/mouse1 /dev/twofingtouch

Add 'twofing --wait' command to start with user session. You can read more about it here. It works on all linux distributives with actual hid_multitouch module.

Brightness

With some Eee PC's, the brightness setting are either too low, or are sometimes a little inconstant or arbitrary (cycling high/low/completely off). If you have issues with this, issue this command to fix it:

And regenerate the grub2 file:

# setpci -s 00:02.0 f4.b=80

The 80 represents the highest brightness level in hexadecimal, which can be replaced with up to FF if desired. 80 is about half, being approximately the same brightness range as windows or grub.

This is not perminent, so it can be added to rc.local:

/etc/rc.d/rc.local
#!/bin/sh

...

setpci -s 00:02.0 f4.b=80
