I am sure there are many who have this same problem. Not being able to run X programs as root because you don't have authority to use X server.
There are always many suggestions regarding the xhost + commands but there is an easier way to get around this (works every time for me)
Run the program as your normal user like so

su "-c <program>"

You then give root password and away you go

or for all you kde users out there:

kdesu <program>

-lakerdonald

[Dapper Dan]

Or for all you SuSE users out there...

 sux -l root

[backtrace]

If you have the GNU Network Object Model Environment installed, use:

gnomesu <command>

If you are in a root shell already and the X credentials weren't transferred over, then you can use the $DISPLAY variable to tell it where your X server is running:

DISPLAY=unix:0.0
or
DISPLAY=127.0.0.1:0.0

The unix one may be a little faster if your kernel supports it.
