Upgrading to 10.04 (Lucid Lynx) on a ThinkPad X200T
Contents
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.
Process
Updating to 10.04 via update-manager.
Issues
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.
Results
Upgrade completes successfully and boots fine. It seems a little slower, but I don't know for sure. So far, all I've needed to do is tweak Gnome a little bit (Move the buttons as at [1], and reset my terminal background).
Screen rotation seems to work fine (the pen rotates as well) using the monitor preferences GUI. Touch is miscalibrated, however, and wacom-tools (and the necessary wacomcpl) does not exist. Calibration can be performed by using xinput_calibrator [2] (make sure device is correct, get the id with --list and use --device id) to get the values, and then calling
xsetwacom set "Serial Wacom Tablet touch" bottomx "value"
for bottomx bottomy topx and topy. Make the calibration permanent by editing /etc/hal/fdi/policy/touchscreen.fdi (reboot not tested yet).
Trackpoint scrolling works.
