Bug Description
I'm running jaunty on my Sony Vaio TZ190N.
Three times in the last two weeks I have experienced a total GUI hang. The screen becomes totally frozen, although the mouse will still move. The keyboard does not respond to ctrl+alt+2 (for example) to switch to a console.
There is nothing of note in /var/log/messages or dmesg or .xsession-errors or /var/log/
It is still possible to ssh into the machine while it is in this state. Killing compiz and gnome-related processes does nothing to the state of the screen. Killing X with -9 as root caused the screen to be corrupted, and the computer to entirely freeze. It was no longer pingable after that.
After a hard reset, the computer was usable again.
