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.
