Let's focus this bug on the problem as it pertains to radeon cards. For people with nvidia hardware seeing corruption on login, please use bug #931967.
These two bugs *might* be one and the same, but until we're certain let's treat them as two driver-specific bugs that just happen to have the same symptoms. The reason is because the bug seems not to affect -intel, -nouveau, or -fglrx. Sarvatt reminds me that -ati has had login corruption in the past. It went away in 11.04/11.10 but he thinks it was just hidden due to the boot speed getting slower in those releases so it would hide the corruption. ** Also 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 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
