You probably need to change your moniter frequencies in your /etc/X11/XFree86Config file. (It might also be called XFree86Config-4 or xorg.conf, I suppose you mean Red Hat 9, and I don't know exactly how it's setup.)

I don't use redhat, so I'm not sure if redhat-config-xfree86 will work in console. Try that first, it might be simpler.

To do this switch to console mode pressing Ctrl+Alt+backspace. Then type
cd /etc/X11
and type ls to see the files in the directory. From this you should be able to see whether you have XFree86Config ,XFree86Config-4, or xorg.conf

Now to edit the file type
nano filename
Find the place that has Section "Moniter" in the file and then look for the lines with HorizSync and VertRefresh. According to this site your moniter should have a HorizSync 30-60 and VertRefresh of 50-120

Then type startx and hopefully your graphics should be working.

What Distro do you use ? Redhat 9.0 or SuSE 9.0 or ... ????

Edit /etc/X11/xorg.conf by following the postings by ntubski. See if there any other references to invalid frequencies (frequencies that are not in the range as specified by your monitor) and modify them.

Otherwise, post the contents of /etc/X11/xorg.conf file here and one of us would have a look and suggest you something useful.
