Initial Conditions

Lenovo ThinkPad X200T (purchased late 2009) with Ubuntu 9.10 (Karmic Koala) installed as per: Installing Ubuntu 9.10 (Karmic Koala) on a ThinkPad X200. Modifications as described on that page: Trackpoint, GPS, screenrotation and touchscreen recalibration. Additional modifications are numerous, and mostly forgotten.


Updating to 10.04 via update-manager.


Installer tells me that 3rd party package distributions are now disabled, but I should be able to re-enable them later if I need. More worrisome, many software are no longer supported by Cannonical, so I fear that I will lose functionality. In particular, I note that bluetooth, wacom-tools, and wine will be uninstalled, but those may be 3rd party.


Upgrade completes successfully and boots fine. It seems a little slower, but I don't know for sure.

Just works

  • Trackpoint scrolling
  • Camera
  • Screen

Minor edits

  • Move the buttons back [1]
  • reset terminal profile
  • bring back volume control [2]
  • change background to 'span'
  • edit startup programs to not do silly things

Major changes

Screen rotation using xrandr and the monitor preferences GUI works fine, rotating the pen and touch inputs as well. However, touch calibration needs fixing. Due to the lack of HAL, the device renaming wacom.fdi doesn't work either, and we cannot use wacamcpl/wacom-tools.

To calibrate, use xinput_calibrator [3]. Make sure you select the right device (get the id with --list and use --device id) to get the values. Calling:

xsetwacom set "Serial Wacom Tablet touch" bottomx "value"

for bottomx bottomy topx and topy will set your calibration.

I haven't figured out how to make the calibration permanent yet.
