Again this advice is good if you know the refresh rate ranges of your
monitor. But if the monitor is a standard one you might go down to 
init level 3 (go to a console and type init 3) and then run:
system-config-display
choosing you monitor and your resolution. ddcprobe will tell you how
much video memory you have if that is an open question.
