Try this, comment out the DPMS line in the xorg.conf file. I know it's
a stupid interelation (power management versus screen mode detection),
but I followed someone else's hint about that, and FC6 stopped resetting
the screen resolution too low on a friend's PC on every X restart or
You might want to post the whole config file that you tried. Do those
options belong with the monitor or video card section? I would have
thought that if you wanted a particular video card not to do some
probing, you'd configure it.
