You didn't install XFree86 from an RPM, did you? Both Xorg and
XFree86 are X server packages. As you have discovered, they do not
co-exist too well together. You may discover other strange problems
down the road. It all depends on what files from Xorg were replaced
with files from XFree86, and how they differ. Xorg was forked off of
XFree86 when the licence for the XFree86 package was changed, and
from what I have read, most of the developers moved to the Xorg, and
development on XFree86 ground to a halt. You may be better off in
the long run to re-install the Xorg packages after removing XFree86.
(It is possible to use rpm to install an already installed package
again, but I do not think yum supports it.)
