Public bug reported: I did fresh install to my laptop today (11.10 i386) and run all the updates. Just after removing Acer AOD250 from external display connection (on-the-fly without first disabling ext display) the GPU locks up (blank screen, just cursor showing up). I did ssh login and system seems to be running just fine - but dmesg list shows that GPU is locked up.
