Bug#483206: [xserver-xorg-video-intel] Xorg: screen gets blank randomly, and there is no way to recover

I also tried suspend-to-RAM, but it didn't bring me back the X console either (and neither did vbetool dpms off/on). I had to reboot (restarting just the X server didn't work either) I don't know how to debug this if it happens again. Any suggestions? Also, I never had such problems before upgrading to version 2.3.1 of the intel video driver. E.g. now sometimes when I login X is killed, and restarted, the 2nd login works fine. Unfortunately it is not always reproducible. I am running a 2.6.26-rc1 kernel, should that matter. Can you try with latest upstream git? Some possibly related lockup were fixed today (see https://bugs.freedesktop.org/show_bug.cgi?id=13326). Yesterday when I logged in, X got restarted again, I looked in Xorg.0.log, and dmesg, and there was nothing related to a crash or restart. The last entries in Xorg.0.log were these: (II) Configured Mouse: ps2EnableDataReporting: succeeded (II) intel(0): xf86UnbindGARTMemory: unbind key 0 (II) intel(0): xf86UnbindGARTMemory: unbind key 1 Today's Xorg.0.log doesn't contain the unbind key message: (II) Configured Mouse: ps2EnableDataReporting: succeeded An older log (Xorg.20.log) shows: (II) Configured Mouse: ps2EnableDataReporting: succeeded (II) intel(0): xf86UnbindGARTMemory: unbind key 5 (II) intel(0): xf86UnbindGARTMemory: unbind key 6 I was not yet able to reproduce the issue today with the debian package. (I did a dist-upgrade this morning, but nothing xorg related). I will try the upstream git, but first I need to find a way to tell wether the bug is still present or not ;) Some things that may somehow be related to such lockups: using EXA (i.e. not having Option AccelMethod XAA), using multiple monitors at the same time, having framebuffercompression enabled, ... I am not using multiple monitors, the problem happens with the laptop's LCD. EXA, and framebuffer compression is enabled, but I didn't explicitly asked for that (default?). Please send the full output of output after running /usr/share/bug/xserver-xorg/script 3 output. Attached, I have run the script when the screen is working. And please do not use reportbug-ng since it does not automatically include all required info that we need to diagnose the problem.
