after workin fine since installation i'm now getting problems with my monitor settings that i'm unable to resolve.
i seem to remember knocking the monitor adjustment controls whilst turning of the machine one night and ever since i get a big blue message in the middle of my screen telling me "out of range" whilst workin on linux (FC4) at 1024 x 768 resalution. If i reset to 800 x 600 the problem goes away but everything becomes huge.
i know that the native re for the monitor is 1024 x 768 and it works fine at this res in windows xp so whats going on??
I've tried fiddling with the screen res usind desktop--preferences--screen res and also desktop--system settings--display but no matter what i do nothing helps
Any ideas??

More than likely that your horizsync and/or vertrefresh in the X11 configuration file are not correct. Please post hardware specs (specifically monitor make/type and videocard) and sections monitor, device and screen from the X11 configuration file (in /etc/X11)

Go to the /etc/X11 directory and change the resolution to 640*480 then you can at least have the X server start. Then I would find out what resolutions are supported for your monitor.

My display settings claim my monitor is a L5AK5 and video card is intel 845.
I know the video card is bog standard as my pc aint flash.
The exact make and model of monitor i'm unsure of cuz i no longer have the box, It's a 15inch flat panel monitor.
I'm fairly certain its native resolution is 1024 x 768 cuz windows xp is running at this resolution with no problems
hope this helps

Sorry that last message appears to have got a bit jumbled in the typing hope it still makes sense

I do not immediately see something wrong in your configuration. If this is your monitor, I would remove the non-supported modes from the subsection with depth 24. The modes-line then will look the same as the modes-line in the subsection for depth 16.Further you can run the xconfiguration utility again. For Fedora I'm not sure what this program is called (in Slackware, it's xorgsetup). First make a backup of the current configuration file.

You might be able to find the correct monitor in windows using the device-manager.

I can't seem to be able to edit the X config file
?? How do i make the adjustments that you sugested

Then move it closer! Ha Ha! Haaaaaaaaaaa!

Um, sorry.

You need to be root to edit system files (use su).

I am also facing same problem.so while installation i choose text method.Then after loagging in single user mode

system-config-display --set-vsync=50-160
system-config-display --set-hsync=30-70
or
system-config-display --set-driver=vesa
It works on fedora .Dont know abt Ubuntu and ........
You can insert values according to your monitor support.

What is the problem? You must be root to be able to edit the config file.
