Installing ubuntu 10.04 on a ThinkPad X201s
This page is just started, and aim to put note to the modifications that should be done to the standard Ubuntu 10.04 installation for a fully functional system.
- Fingerprint reader
- Thinklight (hardware failure on my laptop)
Microphone input jack
The line in / external microphone was not working in the initial installation. Upgrading to the latest version of Alsa solved this problem. 
Follow the guide at Tp smapi to enable the bundled hdaps module.
