Cant change monitor resolution
Im running Debian on a Proliant ML370 but Im having problems with screen resolution. The monitor is a Compaq SVGA (472p). I cannot get anything other than a screen resolution of 640x480. I know its capable of more as when I tested the server with fedora 4 I could happily get 800x600 on the same monitor. Can anyone help? Please make the answer nice and easy to follow as Im still a newbee to Linux :) The following is a copy of the relevant part of the script from the XF86Config-4:

Re: Cant change monitor resolution
This will tell you what is happening during
startup of the x-window system.
I believe ctrl-alt-kp+ will switch available
resolutions.

Re: Cant change monitor resolution
Ive already tried Rick and Steves suggestions. Unfortunatley the on ly option that I have there is for 'screen resolution' and while this is the correct item - it only give me the option of 640x480 - on other option is present - hence my problem.
AS for Bills suggestion - although I can view the file - it has very little meaning to me at the moment so I dont even really know what Im looking for there. (Due to my lack of understanding of linux in general).So I guess I need know what that file is telling me. I'll put up another post shortly and attach the file so you good folk can advise me further :) (Im running this from a workstation not from the server concerend). Thanks anyway for your suggestions.

Re: Cant change monitor resolution
SubSection "Display"
Depth 24
Modes "800x600"
EndSubSection
this should give no choice to X about the screen resolution and depth.
remember to restart the X server.
hth!
ciao

Re: Cant change monitor resolution
Oh my! I answer this question *every* week here.
You need to edit /etc/X11/xorg.conf and add a new modeline. You'll have to use a modeline calculator for that. Look at these threads to find a step-by-step procedure:
