How do i run the x-configuration tool ?

[crazyjedi]

I used to be working quite happily at a resolution of 1024x768 (Which my monitor runs at with xp) but Now however for reasons i'm unsure of, if i set the resolution to anything higher than 800x600 i get a message saying 'out of range' on the screen at all times. How do i run monitor configuration again?
I'm running redhat FC4. My monitor is an Airies L5AK5 15".
I've tried all the usual fiddling with display settings and screen resolution but so far nothing has helped

Try running system-config-display as root

Find out the horizontal and vertical refesh rates for the monitor (from the manual or google search) and edit your xorg.conf file (su - to log in as root and type gedit /etc/X11/xorg.conf). You need to edit the section that looks something like this:

HorizSync 31.5 - 67.0
VertRefresh 50.0 - 75.0

But with your values. Aso make sure that the default setup shows 1024x768. e.g.

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600"
EndSubSection

Update: You can find the details about your monitor here:

http://www.dealtime.co.uk/xPF-Aries_...Monitor_Silver

So according to this the horizonatal and vertical sync values would be:

HorizSync 30.0 - 60.0
VertRefresh 50.0 - 75.0

The recommended resolution for your monitor is only 800x600 but it will support 1024x768 - and as long as you enter this as in the above example everything should work.

Thanks for your efforts so far but i have tried your advice to no avail
I really don't understand it. Linux was running at 1024x768 before with no problems but not any more.
800x600 is huge by comparison and one of the reasons i decided to give linux a try was bceause it is supposed to be far more configurable (if thats a word) than windows. If i can't even get my monitor to run at the same resolution as windows what hope do i have for getting to grips with everything else

Mmm...strange that it doesn't work. Only other thing I can suggest is to add a modeline to your xorg.conf. Under the vertical and horizontal refresh rates add the following line:

Modeline "1024x768_60.00" 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync


and in the screen section delete the reference to 800x600 and change the 1024x768 entry so that it reads "1024x768_60"

nothing seems to work!!
Getting rather frustrated and noe the log-in screen seems to jump about and change position

I'm out of ideas I'm afraid. Could you post your xorg.conf here so I can take a look? Just type cat /etc/X11/xorg.conf in the terminal and copy and paste the output.

ok steve this is the file with the modeline that i tried to put in removed as this was causing the log-in screen to do crazy things

Try amending the screen section so that it looks like the above. Apart from that I can't see any obvious problems.
