Hi. I've got an ISO for quick testing of anaconda's X configuration
setup available that's a little bit smaller than a full tree. All you
should have to do is download the ISO, burn it to a CD, boot and see if
X starts up. Then, you can reboot and go back to your normal doings.
Note that this is entirely non-destructive. So you can even run it if
you are running OS X. *ANY* results would be helpful. Please be sure
to include what you see happen as well as what type of hardware you're
using (cpu, video, monitor).
