AMD should make that the default till they fix their buggy xrandr implementation.

I managed to get the "Big Desktop" option to appear and remain an option in Catalyst, but every time I logout or reboot the system, the "clone 1" option is replacing my settings which work perfectly while logged in. I ran amdcccle as super-user and my user account and still have the same result. The Gnome login window after reboot/logout recognizes the new settings (login is on left screen, right screen black).

I am running Ubuntu Jaunty 64-bit system, using a ATI Radeon HD 3600, installed driver version 8.65, catalyst 9.9.
