Lenovo ThinkPad Edge 13
How to setup Arch Linux on Lenovo ThinkPad Edge 13. This guide has been written aside the ThinkPad Edge AMD version with ATI-graphics.
This article was written to assist you with getting Arch Linux run on the Lenovo ThinkPad Edge 13.
Prerequisits
First and important to do is an BIOS-Update (As of 2010/08/20 to Version 1.19.)
This was done, by using grub4dos, one can get here. Because a simple dd did not create a bootable USB-Stick for me.
BIOS-Update:
Download grub4dos.
Unpack it on another *nix-box and run:
# ./bootlace.com /dev/sdX
with /dev/sdX being your USB-Stick (as the Thinkpad Edge 13 has no CDROM-Drive) in the directory, where you unpacked your files.
Afterwards copy grldr and menu.lst to the device:
$ cp grldr /media/USBSTICK $ cp menu.lst /media/USBSTICK
Download the BIOS update from the BIOS section on this support site. Pick the one that matches your current BIOS Id. Copy the iso-file to the / directory of the USB-Stick!
Finally you have to add the following code to the menu.lst on your pendrive to make the USB-Stick boot the PC DOS program made by lenovo:
title Thinkpad-Edge-BIOS-UPDATE find --set-root /6yuj06uc.iso map /6yuj06uc.iso (0xff) || map --mem /6yuj06uc.iso (0xff) map --hook chainloader (0xff) boot
Inserting such a prepared USB-Stick into your Thinkpad Edge, and things should be self-explanatory after that.

Installation
WLAN deauthentication issues
If you are using the rtl8192ce module, you may experience some intermittent deauthentication issues with newer kernels (tested on 3.4.4-2-ARCH). The reason is because the BIOS is turning off the wireless card when the BIOS deems it to be "inactive." This is the case if dmesg reports
[ 285.140301] wlan0: deauthenticating from MAC by local choice (reason=3)
A simple solution to this problem is to enter the BIOS setup and disable PCI Express power management.
Audio
To get jack sensing to work add:
options snd-hda-intel model="olpc-xo-1_5"
to /etc/modprobe.d/modprobe.conf.
Video
If you have the AMD-AMD model you can use the free ati drivers. Install xorg-server xf86-video-ati.
These drivers give enough horsepower for compiz and video playback.
Touchpad
A synaptics touchpad with two-finger scrolling. Install xf86-input-synaptics.
Frequency scaling
The Turion work well with powernow-k8. Please refer to the wiki for more information on cpufrequtils. Dont forget to add powernow-k8 to your modules array.
Fan control
Add the follwing line to your /etc/modprobe.d/modprobe.conf
options thinkpad_acpi fan_control=1
Then you can manually set your fanspeed with:
# echo level 7 > /proc/acpi/ibm/fan $ cat /proc/acpi/ibm/fan # for more commands.
Other files will report their status and commands when read too.
Webcam
Works out of the box. Test with
$ mplayer tv:// -tv driver=v4l2
If you use skype and the video is way to dark, skype forgot to enable automatic exposure control. Install v4l2 control and set it yourself. You need to to do it everytime you use skype. Install v4l-utils, then:
$ v4l2-ctl -c exposure_auto_priority 1
Your video should gradually begin to brighten up. More options:
$ v4l2-ctl -l
Suspend
First, you might need to add the following to your kernel commandline if suspend does not work. Newer models do not require the following hacks, so make sure that neither suspend nor wifi works.
kernel root= ... acpi_osi=linux noapic
Second, your wifi card will delay resume by roughly 2 minutes. That means that your laptop is not frozen but still resuming. Wifi wont want to work, too. This can be worked around by removing the wifi modules before suspend. You can do this automatically if you use pm-utils. Please refer for more information to the pm-utils wiki article. Below follows a /etc/pm/sleep.d/100wifiworkaround.sh script for automation
#!/bin/bash

Troubleshooting
High power consumption
In some cases you may experience high power consumption despite of all BIOS powersaving functions turned on.
This is because the BIOS settings do not really disable the dedicated video card, they just force the notebook to use the integrated graphics.
The solution is simple: enable video card switching and use system means (vgaswitcheroo?) to disable dedicated graphics.
