Easy.

Before suing over to root, run:

xhost +

Then su over to root and run the command.

The X windows system display security in based on user privs more than 
the machine and display.  The xhost + command turns off the X display 
security allowing any user on the system (or machine on your LAN) to run 
a program and have any X output show up on your display.

Of course, the user or machine has to specifically point their display 
environment variable to your active X display, but it /might/ be 
something to keep in mind.
