Make sure you look up proper monitor settings:

Then in XF86Config, edit the file to set your XF86Config file to ensure that
your mode statement matches one your monitor supports, and set the color
depth to 15 not 16 (I don't know why) and that should work. Here is my
section (it may be different because I have XFree86 4.01)

   Section "Screen"
    Driver "fbdev"
    Device "control"
    Monitor "My Monitor"
    DefaultDepth 15
    Subsection "Display"
        Depth 15
        Modes "1152x864"
        ViewPort 0 0
        Virtual 1152 864
