I agree, for me it's "mostly" when the system has been running for a while, so I've seen it 2-3 times first thing in the morning when the system has been left running overnight.
I'm able to ssh into the machine and poke about, look at logs, report bugs etc, but the display is hung. Unfortunately I'm travelling at the moment so not much chance of having a system running for very long. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/868684 Title: vblank counter failed - screen hung Status in X.org xf86-video-intel: New Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: Just came back to the screen to find it hung, I could still move the mouse but nothing else.
