I notice what appears to be the same thing in Precise. In case it helps, my specifics:
- everything is visually fine from boot to presentation of login screen - after I type my password, before the gray intermediate screen comes up (between login and session) in Unity 2d, my screen flickers briefly and then for about 5 seconds shows multiple corrupted password dialogue boxes scattered around the top of the screen - my hardware is old ATI IGP stuff - one other thing that I notice that is different than 11.10, and that is my session background also appears as my login background; that is, I chose the "watch gears" background for my session, and afterwards, whenever I see a login screen, it also has "watch gears" -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/933322 Title: LightDM graphic corruption with ati and nvidia To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/933322/+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
