** Attachment added: "end of dmesg showing hung task warnings"
   http://launchpadlibrarian.net/32865078/dmesg-fragment

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  If I leave the machine alone for long enough, I'll return to a blank
  (black) screen and unresponsive mouse and keyboard.  Disabling the
  screen saver seems to work around the problem.  I can still ssh in after
  the problem occurs, and see hung-task warnings in dmesg (see attached
  dmesg-fragment).  As you can see, the tasks involved are i915/0, Xorg,
  and lorenz (the screensaver).
  
- I'm running karmic, xserver-xorg-video-intel version 2:2.6.3-0ubuntu9.3,
- kernel 2.6.28-15, lspci reports the video as GM965/GL960.
+ I'm running karmic, xserver-xorg-video-intel version 2:2.8.1-1ubuntu2,
+ kernel 2.6.31-11, lspci reports video controller as "Intel Corporation
+ Mobile 4 Series Chipset Integrated Graphics Controller (rev 7)."
