Hmm...  Hopefully the other lists were a little more responsive...
But, since there hasn't been any follow-up posting, I assume you're still
without a solution.

You don't say what kind of video hardware you have...  What sort of video
card?  How much memory does it have?  What sort of monitor?  What's its max

When you ran the RH 7.1 installer, or Xconfigurator, did they correctly
detect the card, and the amount of video memory you have?  Were you able to
select your monitor from the list of available choices?  If not, did you
select a "Custom" monitor type, and key in the H-sync and V-sync ranges, as
indicated in your monitor's technical specs (in its manual)?

It's hard to know what to recommend as a solution without knowing what
you're dealing with as far as setup, and what you've already tried to do.

If the installer and/or Xconfigurator are guessing any of the settings
wrong, you may have to tweak the configuration after the fact by going in to
/etc/X11/XF86Config-4 with a text editor, and adjusting the incorrect
settings.  Hsync and Vsync settings should be easy to find in the Monitor
section of the file, and easy to set if you've got the manual or can find
the technical specs somewhere.

It's also possible that your video card is just not well supported by
XFree86, and you may have better luck with a different card.

Good luck!
