first turn off your X (ctrl+alt+f1, /etc/init.d/gdm stop, or kdm or whatever
you use).
X -configure
turn on your X (startx or /etc/init.d/gdm start)

which vga are you using (model/version/revision)?
lspci | grep VGA

EDID has a bug with some intel and ati cards. EDID is responsible to
identify a lot of informations about your monitor. Some developers are
fixing this problem.
