Monitor garbled after RedHat9 install.
 

Hi,
I recently bought a Lindows box that worked fine with my monitor. I discovered though for ease of Oracle database installation that I should have Redhat 9 instead. So I did a full install, overwriting Lindows.
The install appeared to have gone successfully except aside from the core start up processes when I boot my machine, the screen is completely garbled. I remember that the install process at the beginning recognized the video driver, but not my older monitor. Any clues what I'll need to do to have a usable screen again? I can see that something is trying to display and that if I move the mouse around it does show that something is moving on the screen, it's just a big repeating fuzzy mess.
Thanks for any suggestions you might have for resolving this.
Kurt
