[Bug 461183] [NEW] Switching users in gnome locks machine when using ATI/AMD proprietary FGLRX graphics drivers

 

You have been subscribed to a public bug:

On an iMac (generation iMac7,1), using the proprietary ATI/AMD FGLRX
graphics drivers, switching users will cause the machine to lock solid
(no response to keyboard, mouse, no alt-F1 console switching, caps-lock
light does not activate when pressing caps-lock, and active remote SSH
connections are severed).

One solution is to remove the proprietary drivers using the System > Administration > Hardware Drivers tool, which removes the following packages:
fglrx-amdcccle
fglrx-kernel-source

(However, Hardware Drivers tool warns that the proprietary driver may be
needed for 2D and 3D support.)
