I'm seeing this too. It happens randomly and when the hang happens the blocks on the screen are pretty much as in the video on the launchpad bug. The laptop is a Lenovo T60 running at 1024x768.
lspci output is:
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03)
It seems to happen more often when a composite manager is being used but I have also had this happen when logging out of sessions that have only been using metacity. It does not seem to happen every time. I am currently trailing whether this happens when DRI is disabled.
Version information:
xorg 1:7.2-5ubuntu7
xserver-xorg-video-intel 2:2.1.1-0ubuntu2
