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)
