[ltp] T510 lockup on Ubuntu 10.04

[Paul Fisher]

Has anybody else ever experienced screen lockups on the T510?

I'm running Ubuntu 10.04 with the NVidia chipset open-source video
drivers, and every once in a while the screen will just stop accepting
any input from the mouse or keyboard, as if something had grabbed the
cursor and would not release it for anything else to use.

The screen freezes, and nothing is drawn to it except the cursor.  I can
still move the mouse around the screen, but I can't make any input.
Programs still seem to run in the background (for instance, a video
might freeze-frame, but the audio blithely continues to play).  I can't
even switch to a virtual terminal using ctrl-alt-F#.

There is nothing in syslog, kern.log, or any other logs that coincides
with the time of the lockup.

Does anybody recognize these symptoms, or have any advice for teasing
out more useful information?

Thanks!
