The standard Debian drivers are intentionally limited to low resolutions, so they work with practically all video chips. If you want higher resolutions, install the (propriety) driver from your videocard manufacturer.

First, 1024x750 is not a standard format. Monitors are typically 4:3, 16:10, or 16:9.

The normal practice would be to set the highest resolution in xorg.conf. X then figures out the lower modes. Sometimes, however, you need a "modeline".

Have you tried running xorgconfig?
What is your video card and monitor?
Post the Monitor, Device, and Screen sections of xorg.conf

Where on earth did it get those weird modes?

Suggestion:
Delete all the subsections with modes except for depth 24 (the default). In that subsection put ONLY the highest res mode you plan to use. Be sure it is a standard mode consistent with your monitor.

For more help, tell us what you monitor is...

ahmed gamal · 03-07-2008, 03:35 PM

my monitor is hansol 401A
i am sorry i didn't understand what to do ???

Google found this:

Your monitor goes to 1024x768

In the screen section of xorg.conf, delete all the sub-sections except for the one for 24 bits. Edit the the one remaining subsection so it looks like this:

Code:

SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection

For more details do:
man xorg.conf
