Bug Description

my system was up-to-date, I was just getting a fresh apt-get upgrade in a gnome-terminal, and listening to banshee, when boom... it all went black... I could not access my system, I could not restart X with Ctlr+Alt+Bckspc, or change to a textual shell with Ctlr+Alt+F2... I had to remotely access the box via SSH... killing gdm and X was not enough, so eventually I gave up and rebooted the system to file this bug repport

You should also check your dmesg and /sys/kernel/debug/dri/0/i915_error_state when you ssh into it when it's down, in the case that the issue is a gpu lockup.

Similarly to other intel related bugs, I will try to post the collected data
when my box freezes again... not sure how it will behave with a newly
upgraded kernel, though...

I have been trying to get reproduce the bug to capture dmesg, i915_error_state and even backtraces from my gdm session, but I am not sure what triggers it yet.

So far, it seems that it freezes when the screensaver was running for some time BECAUSE IT HAD TURNED MY SCREEN OFF due to energy policy...

I had since disengaged the energy control option to never turn my screen off again, so far it has not frozen my system again. I suspect that this could be the root cause, but I am not sure how to prove it, or what packages could be involved to further the investigation.

It also seems to happen only on my systems with intel video boards (Mobile GM965/GL960 Lenovo Laptop and Mobile 945GME Express Asus netbook).
