At the risk of being way off the mark, I'll mention my recent similiar
experience with Slackware 9.0 at home. By default, X drove the monitor at an
extraordinarily high resolution, one that I didn't even think my graphics card
and monitor could support. I think that without guidance XFree86 will use the
highest possible resolution it can for the detected video card and monitor. I
edited the XF86Config file to add these lines to the file:
Depth 24
Modes "1280x1024"
That fixed the display at 1280x1024 in 24-bit mode. The VESA standard modes
are available even if they aren't defined in the file. These go under the
Section Screen, SubSection Display for the active display. XFree86 will let
you set the depth on the command line, but apparently not the resolution.
