I have installed Fedora Core 2 and when I boot, I get my screen all ‘torn apart’. Fedora correctly recognized my videocard (ATI mobility 128mb) and I have manually selected my display (Dell 104 x 768 Laptop LCD).
The funny thing is, when there is an external monitor connected and you press the FN key to select to output on both displays …. The screen is perfect on the laptop. When I boot without an external monitor connected, the screen is unreadable again.
Can you advise me on what to do, where to look ????
