If i start two x-sessions I can run one on each screen. The one i run in
1024x768 Is on both screens because both screens support it. And the other session
runs 1280x1024 And is only displayed on the external screen. (1280x1024 is not 
supported by the internal screen).
It must be a way to do this but with only one x-session.
