Lenovo ThinkPad X200
The Lenovo ThinkPad X200 is a wonderful high-quality laptop featuring a 12.1" widescreen WXGA monitor, an Intel Core 2 Duo processor (2.26 - 2.66GHz), an Intel Graphics Media Accelerator 4500MHD and up to 4GB of RAM whilst still maintaining impressive battery life.
While Arch Linux is running flawlessly on this Laptop there are a few things you have to configure manually. This article will aid you in configuring your system and will provide additionally hints to make your ThinkPad X200 experience even better.
The ThinkPad X200 has a Intel PRO/Wireless 5100 AGN wireless adapter included. In order to make it work you have to install the iwlwifi-5000-ucode package from the core repository to get the firmware.
# pacman -Sy iwlwifi-5000-ucode
From there you can choose whatever network configuration programs you want to use. If you don't already know which network manager you want to use, we highly recommend netcfg.
The graphics card is supported by the xf86-video-intel driver package from the extra repository. The Xorg server makes use of this automatically. There's no need for a Xorg configuration file.
# pacman -Sy xf86-video-intel
However, with the newest available driver version it seems as if a regression has been introduced resulting in poor 3D performance. You will experience Xorg running fine, but 3D applications will have a very low frame rate.
Audio is supported out of the box after installing the necessary alsa packages from the core repository.
# sudo pacman -Sy alsa-lib
See Alsa for more information.
Suspend to RAM
Suspend to RAM is working out of the box with the standard Arch Linux kernel after installing pm-utils from extra.
# pacman -Sy pm-utils
Issue the command
as root to suspend to RAM. The laptop will wake up on any key press or on opening the lid.
Note: Very seldom after resuming the backlight won't come back on. The following page on ThinkWiki might provide information on how to solve this issue: Problem with display remaining black after resume.
