Some notes to get Arch Linux running on a Thinkpad X40.
TODO

Not fnished yet. I'm documenting the installation process as it goes

Contents
Preface
I downloaded the FTP installation CD on http://www.archlinux.org/
Wireless
My main concern was getting the WIFI to work. As the downloaded ISO also functions as a livecd, I tried to get it up and running with that. Without success. I found the answer to my question here: http://bbs.archlinux.org/viewtopic.php?pid=482359
I installed madwifi and madwifi-utils. In the modules section of /etc/rc.conf I banged the ath5k module, disabling it. With ath5k not banged the card showed up as wlan0, associated correctly with the AP, but didn't get a DHCP lease. Even with manually setting the IP and adding the default route, I couldn't ping the AP.
After banging ath5k, the wireless card shows up as ath0. Associating works, DHCP doesn't time out. :)
Power Managerment
The two most important factors of a mobile device are battery life and weight. I'm always a bit disgrunted when an advertisement doesn't mention one or either.
Without any powersaving installations the 8cell battery still managed for a nice 4 hours.
CPU Frequency Scaling
CPU Frequency Scaling is a technology primarily for notebooks that enables the OS to scale the CPU speed to system and/or power use.
I simply followed the following instructions: http://wiki.archlinux.org/index.php/Cpufrequtils
Suspend
I tried pm-utils. 2
# pacman -S pm-utils
I added following modules to the /etc/pm/config.d/config file:
SUSPEND_MODULES="wlan_wep wlan_scan_sta ath_rate_sample ath_pci wlan ath_hal"
But suspending seems to work even without this.
The backlight wasn't working when resuming from suspend, but the following fixed it [1]:
#!/bin/bash case $1 in suspend) ;; resume) chvt 1 vbetool post & sleep 1 kill $! chvt 7 ;; esac
Xorg
Installed xorg with
# pacman -S xorg
Then generated the xorg.cong file with
# hwd -xa
(I know, risky ;))
Looked good, but X didn't start with this (couldn't find display). I installed the xf86-video-intel and changed the display driver from i810 to intel in /etc/X11/xorg.conf:
Section "Device" Identifier "Card0" Driver "intel" VendorName "All" BoardName "All" EndSection
Getting the back/forward special keys to work
Add the following to your ~/.Xmodmap 1
keycode 77 = Num_Lock keycode 234 = XF86Back keycode 233 = XF86Forward
Enabling scrolling with middle mouse button
Add the following to your /etc/X11/xorg.conf, to the PS/2 mouse section 1
Option "EmulateWheel" "true" Option "EmulateWheelButton" "2"
Postface
Don't forget to run:
# alsaconf
to get the sound to work properly.
