I'm writting this for a good friend of mine who has just installed redhat linux 8 a week ago and is already having a problem, the problem is that instead of getting the graphical login screen he gets the text only and every few seconds the screen jumps. I read a bit on the net and foundout that it's most probably a problem with the x-windows settings, both he & I have no linux knowledge, I tried using the rescue console and typing xf86config but no-go. If anyone could give me step by step instructions (and the commands) to restore/change back the settings my friend and I would be very greatful. I also read that you need to change the runlevel (he uses grub so we need to edit the run command and add the runlevel at the end but that's all I know).
Thanks in advance!
