OK, was installing RH7.3 on my laptop, got to the end where you test your monitor settings, well, they were not right, and it never went back to normal. I tried enter, tabbing and enter, etc etc, but no luck. So I restarted. I can get to a prompt and whatnot. How can I set this up manually? I have found some things in /etc/X11/ but I don't really know what to do. Any help?
