Public bug reported: Problem began playing a dvd with xbmc on dual screen setup. Everything was fine, until I moved the mouse trying to get to the playback controls. Then picture froze and after every few seconds the screens blinked off and back again, with some temporary graphical glitches. This persisted until I kill -9:ed xbmc, after which things seemed to normalize. Trying to open a new window caused the same blink again, but very slowly the terminal appeared. When the glitches didn't go away, I tried restarting lightdm, but it only managed to stop, not start again. However the console was still working.
After a while, "start lightdm" did work again. ** Affects: xserver-xorg-video-ati (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1076288 Title: Radeon driver starts freezing and dies To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1076288/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
