Do you have the latest and greatest Radeon driver installed, or using
the default driver installed when you installed Lucid?
I have similar hassle with my 1920x1080 Viewsonic if I don't install the
latest nVidia driver for my video card; install the 'proppa' driver and
then I'm at the native resolution.
Paranoia is simply an optimistic outlook on life.
