    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.
