I enabled Xinerama and now I cant do anything. All that shows up is my mouse and background. Step by step how do I get back to normal?

I also tried opening up programs, perhaps to open Catalyst but I cant even do that. And none of the keyboard shortcuts I have tried did anything, as well I can not find a keyboard shortcut to open the terminal to kill this thing. Thank you for the help.

I found the answer myself. It is: CTRL+ALT+F5. Then sudo aticonfig --xinerama=o

The right command is: sudo aticonfig --xinerama=off – user48870 Mar 2 '12 at 15:05
