Changing the screen resolution?

Hello everyone Finished installing RH9. Nothing went wrong. All was fine! I was scared for a moment. Windoze left me this type of scar, everything's always going wrong.

Anyways, when I'm in, I try to change the screen resolution in the display properties, switching it from 800x600 to 1024x768. Well, I'm trying, because whatever I do it switches it back to 800x600.

Here's what I do: I change the tab from 800x600 to 1024x768, and then it tells me it saved it, but I have to reboot my X. So I hit Ctrl+Alt+Backspace, but it won't change it. A simple reboot won't do the trick either. Why?

Additional note: In my display properties, it says "Undetected monitor". Could it be my problem?

Thanks for your interest, but I have found my problem, it was indeed the Undetected monitor I had to change. I set it to Generic Monitor, 1280x1024: 60 hz. I have an Optiquest 17". Was it the good choice?

Did you check the Optiquest list in RedHat's XFree GUI tool to see if your monitor is available ?

In the menu, System Settings -> Display
At the command line, type: redhat-config-xfree86

Or if you know the frequency range of your monitor, you can always edit /etc/X11/XF86Config and modify the monitor section by adding the corresponding HorizSync and VertRefresh.
