Hi
I have Red Hat Linux 7.1 installed on my system(with an intel 810 Motherboard and onboard graphics). my problem is that when i am working in linux, the screen suddenly goes blank for a couple of seconds even when the computer is not idle. someone told me that it was due to wrong refresh rates but i put in the correct horizontal & vertical rates(from my monitor's manual) in the Xconfigurator tool but still the problem persists. pls help me.
