I am experiencing this bug as well, though with an Acer laptop, no touch
screen.  random lockups where the mouse still works.  fiddling with tty1
has mixed results -- killall on compiz to avoid a hard reboot would work
for a bit, but after a couple of hits of that, things just went weird in
the way of it just giving me the stock orange background image, or
performing very slowly.  I switched from firefox usage to chrome and
that seemed to help.  the last day I was using firefox, this lockup
happened 3 times in one morning.  normally after my screen sleeps from
inactivity.  but sometimes while I'm actively using the laptop.  after 5
days of no issues in using chrome, it happened again.    I've downloaded
the compiz config app and disabled animations.  hoping that will avoid
the problem.

Title:
  [i945 GMA950] X freezes about once a week

Status in xserver-xorg-video-intel package in Ubuntu:
  Invalid

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/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.
