"gnome-session:you're already running a session manager" Red Hat 8

I am running the same setup, i.e. Red Hat 8.0 with VNC server and XP/NT
clients.  I had the same issue until I started the server as a different
user.  It is conflicting with the gnome-session already running as root and
gnome has no facility to run multilple sessions (i.e. different displays) as
the same user.  If you want the VNC session to be root, then I would run the
console in text mode only and don't start X when linux starts.  Mine runs
fine when I start Xvnc as a different user other than I get the memory leak
problems already mentioned in this list when running certain gnome apps.  I
just avoid them.
