Comment 9 for bug 868684

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.
