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). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767427 Title: [i965gm] GPU lockup -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
