I've gone and set my monitor to a res/refresh that linux thinks it can't handle, though it can in windows. I have to use a generic driver as there isn't one available for my monitor, Samsung Syncmaster 955DF.
How can I get it back to the default, at least, res so I can reset it? I boot to to prompt but I'm new at this and don't know how to edit the cfg that way.
Any help would be greatly appreciated.
I'm running Redhat 9/GNOME btw.

Login as root and:
vi /etc/X11/XF86Config-4
You should now be looking at your X configuration file. Scroll down to the monitor section, and make the necessary changes (press "i" to insert text).
When you are done, press ESC to enter "command mode" and then type
:wq
Which will write the file to disk and quit vi.
Then try to start X again.

Actually, now I have another question:
I can run quake3 in windows 2000 at 800x600 @ 120hz. My monitor supports that res/refresh combo but what went wrong was me putting in the wrong horizontal refresh. The factory timings, according to the display panel on the monitor, doesn't list the refresh rate for that res, though it does list 120hz vert/77.1 horiz NP, whatever that means.
If I just boot into windows, load q3 at that res, view display timings to get horiz refresh, where do I put that as a possible res/refresh combination? In XF86Config? (it's not XF86Config-4 btw, tripped me up at first).
Search in your XF86Config for: HorizSync and VertRefresh.

I think I got it. Horizsync/Vertrefresh is the spectrum that the monitor can handle, correct? And then when res is changed the monitor will load what it thinks is the highest refresh for that res, given the modes available under Screen0?
q3 was running at 800x600 @ 85 hz in linux. So how was I able to get it to run at 120 in win2000? Is it because thats the limits of the generic mon driver? Similar things would happen if I left the monitor plugnplay in windows and didn't install the proper driver.
So...guess I'm out of luck unless a driver is released huh?
You also might find it easier to configure your XF86Config file by typing "xf86config" at the console, which is a question and list-driven XF86Config configuration tool.

I think I got it. I just need a driver that will allow me to run 800x600 @ 120hz :( :(
