Comment 5 for bug 404331

Couldn't install upgrades with build-dep or aptitude, so upgraded to 8.10 Intrepid, xserver-xorg-core 2:1.5.2-2ubuntu3.1 , xserver-xorg-video-ati 1:6.9.0+git20081003.f9826a56-0ubuntu2.1. Very similar effect has occurred once, (although cursor movement was slow/jerky after lockup this time).
