I have installed Ubuntu 10.04 on my X200 and most things worked out of the box. The only major thing that needed fixing was the rotation of the wacom and the calibration, which was easily fixed by following the instructions here: Installing Ubuntu 10.04 (Lucid Lynx) on a ThinkPad X61 Tablet - ThinkWiki The only thing I cannot get to work is the tablet buttons. And I am interested especially in the Rotate button. Has anyone found a solution to this? Thanks in advance.
