I changed the display settings from 640x480 256colors to 1024x800(thousands of colors) or something like that... Well the problem is now when I boot KDE won't load. It goes through everything but when the GUI is supposed to load my monitor turns off and nothing happens. How do I change back to 640x480 without reinstalling RedHat? Thanks....... (Sorry for dumb question, I'm new to linux.)

type as root xf86config and set it up properly ..

Thanks for the quick reply but -- It says "command not found"... ???

damn redhat ...
well i am going to throw this one off the top of my head, so your just going to have to try and see if it works, cause i am just trying to remember, but try typing :
redhat-config-xfree86
i am sure if i am way out in left field that someone will correct me..

I have a simular problem (in an other thread). its says theres an error with my frequency range, so i tried what you said, the redhat-config-xfree86 (i was origonally told to try xf86cfg like you did). redhat-config-xfree86 works, except i still get the out of frequency range error, it might work for your problem though.

First, find out the frequency range for your monitor. Applying incorrect horizonal &/or vertical frequencies may have dire consequences (you'll fry the monitor) - take a look @ the back of your monitor on the manufacturers label for info, if not there, look on manufacturers web-site.

If you cannot find commmand xf86config try typing in terminal =>
whereis xf86config

This should show you the path of xf86config executable. Type the full path upto & including xf86config, and follow on screen prompts.

Ok redhat-config-xfree86 works, sort of!... it tries to run something but the screen goes blank and the monitor light turns from green to orange.... *kills redhat*

you need to edit the file /etc/X11/XF86Config and change the section "monitor"
(file might be called /etc/X11/XF86Config-4 if you can't find the above file)

Section "Monitor"
...
HorizSync 31.5 - 35.0
VertRefresh 50.0 - 75.0
...
EndSection

Values like that should be low enough for you to at least get your display back. if you know the H and V rates for your monitor enter them instead (but do NOT guess)


and then in the screen section...

Section "Screen"
...
DefaultDepth 8
SubSection "Display"
Depth 8
Modes "640x480"
EndSubSection
...
EndSection

NOTE: the 3 dots (...) in each section imply that you will have something here in your file that doesn't need changing. Just copying and pasting these lines will not work. Use them as a template.

Yeah... So... Pretty much nothing I tried worked. So I'm sticking to XP and SuSe, cause this is the second time RedHat took a shit on my system.
