Please I need help to restore my monitor display
I am new to Linux and most recently I installed RHEL 3 on my hp pavillion ZV5000, I couldn't get a complete display on my monitor and when I checked x windows my monitor was detected as unprobed, so I selected the "Generic LCD 1024 X 728". Which, i was promted to log out for settings to be in effect. After logging out, I can hardly see any display on my monitor (it's all dark). I really don't wish to re-install my system yet, becos I have got some important files that I recently transferred there. Pls can someone at least give me a clue that I can apply to restore it to it's former settings?
