I would not recommend this if your connected to a network like the
internet. Better read "man xauth".

I suggest you write a little shellscript for root, that automates
xauth-authorization like this:


#!/bin/sh
# xauth4root - sets Xauthority the way I want it
export DISPLAY=:0.0
xauth -f /home/YOUR_USERNAME_HERE/.Xauthority extract - $DISPLAY | xauth merge -
$*


Then you can start e.g gvim with:
% xauth4root gvim
