Ok, So I installed ATI Livna Drivers and my display looks great and I am running dual monitors on a laptop. The normal monitor and an external 27".
The strange part is the keyboard only works on one monitor.
The mouse works on both.
On the external monitor I can open application but only with the mouse and the application windows do not have a border. The top area that says openSuse an enables you do move the window around.
It isnt there. It tried alt +f3, but as I said the keyboard only works on display1 (laptop). Therefor all key commands revert back to the laptop monitor.
It sounds like you have it setup to have two seperate X sessions. There are two ways to setup dual monitors. one is to have a single X session span the two monitors. The other is to have two seperate X sessions.
I don’t know about the ATI drivers. But you should be able change it in sax2. (in YaST or console window by typing sax2)
