X must not know what sort of monitor you have (and maybe doesn't know
what capabilities your video adapter has). Open the file
/etc/X11/xorg.cong or /etc/X11/xfree86.conf or whatever is there.

You should have something that says Section "Screen", below there should
be all the modes that X is set up to perform. Here's mine:

Section "Screen"
         Identifier "Screen 1"
         Device "My Adapter"
         Monitor "My Monitor"
         DefaultDepth 24
         Subsection "Display"
                 Depth 16
                 Modes "1280x1024" "1024x768" "800x600" "640x480"
         EndSubsection
         Subsection "Display"
                 Depth 32
                 Modes "1280x1024" "1024x768" "800x600" "640x480"
         EndSubsection
EndSection

X will always try the first listed mode. Also, make sure your monitor is
set up correctly. You should be aware of what frequencies it can take.
Mine looks like this:

Section "Monitor"
         Identifier "My Monitor"
         HorizSync 31.5 - 128.5
         VertRefresh 60 - 75
EndSection

If your monitor is capable of producing 1280x1024, use the settings
above (or adjust your VertRefresh if you know it can handle more).

Hope this helps. There are also other tools which allow a frontend for
editing this file, but this way you understand what is actually happening.

Dave.
