Comment 9 for bug 760769

I'm getting this about once or twice a day. Will just turn around and come back to my laptop, (Dell 1420N - Intel Graphics) and the UI will be frozen - clock is froze, mouse moves, and I can switch to a console but I haven't been able to kill the session to get back on, other than by rebooting from the command line.

I'll be happy to collect some debugging info from the command line next time it happens if I get instructions.
