monitor displays nothing after logon
I have Fedora core 3 installed. I changed the monitor config to "generic 1024x768". Now after the user is logged on the monitor displays nothing. The monitor is an older NCR 15in monitor. After the logon all the lights on the monitor flash (this means the is an incompatibility between what the system is set for and what the monitor will except). How do I boot to a point where I can correct the problem and go back to "undefined" at 800x600 (atleast that works)?
