I see this with 7900 GS. [drm] nouveau 0000:01:00.0: fail pre-validate sync [drm] nouveau 0000:01:00.0: validate vram_list [drm] nouveau 0000:01:00.0: validate: -16
I think "hang" is too strong a word for this problem. The mouse pointer is still active, which may matter quite a lot in debugging this. A hang where the entire display is frozen, pointer included, is more dire. ** Summary changed: - [7300 GS] Intermittent GUI hangs in 12.04 + [7300 GS, 7900 GS] Intermittent GUI hangs in 12.04 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/994306 Title: [7300 GS, 7900 GS] Intermittent GUI hangs in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/994306/+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
