[Bug 339982] Re: [i945 GMA950] X freezes about once a week

[Bryce Harrington]

** Description changed:

  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/Xorg.0.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.
