So, you want to something like
export XAUTHORITY=~user/.Xauthority
where `user' is the name of the user that is logged in to the X display?
Don't do that. The minute root writes to that file (when root logs in to X
or uses the xauth command), it becomes owned by root and the user can't
log in to X anymore.
What you could do is using ssh. This command will do the trick:
xterm -title Root -n Root -e ssh -l root localhost
You can add it to a Fvwm(1,2,2-95) menu or button bar.
ssh will take care of X forwarding automatically, no matter if you
'connect' to the localhost or another host. In any ssh session, you can
simply do something like "xterm &" and the window will appear on the local
screen.
