I have a Linux RH9 box running as a squid proxy. I was messing around with the services and was turning off unnecessary (or so I thought) services and realized I had turned off x-windows, stopping all ability to run a GUI (as you can see I'm a little new at this). I turned "ALL" services back on and video was restored. Now a strange thing happens. When I log off my box to return to the Logon screen, the screen goes to "black" again. The system is still running. The light on my monitor is green (indicatiing it is receiving a signal from the computer). The only way to restore video is to restart the machine, via remotely or via the power button.
Has anyone had the problem before, any suggestion?
