Matt, was the battery on your ThinkPad not attached when you weren't able to reproduce the hang?
When I was trying to get the hang to happen on my X200, I got about two days of hang-free Unity. When I attached the battery and continued trying, I got two hangs within three hours of each other. It doesn't make sense to me that the two are related, but it may be worth a try. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/966744 Title: [i965] Resume from suspend leaves me with black screen or a screen of the desktop before it suspended.
