Usually this means you need to specify your horizontal
and vertical sync and refresh rates.
I would run:
X -configure
cp xorg.conf.new /etc/X11/xorg.conf
then add some lines like:
Section "Monitor"
Identifier "Barfy"
HorizSync 31-92 # Taken from my monitor,
VertRefresh 55-160 # Don't use these values.
EndSection
and change
Section "Screen"
Monitor "Barfy"
Frequently on older cards the monitor's capabilities
cannot be detected which can lead to very conservative
defaults which can lead to no valid modes.
There is a database of these values (I've found it to be
accurate, if incomplete):
