That's ok. When you use su(1) to become root, you no longer have
permission to open programs on the display of the X server opened
by the plain user.

Open another xterm, from the X11 session of the plain user, and run:
$ xhost +localhost
Then you'll be able to `connect' by running as root:
xenon# setenv DISPLAY localhost:0

That may be true, depending on the version of X11 that you are
running, the current operating system and the setup of the X11
sessions. I can't tell what you had done, since I wasn't there...

Sure. Keeping notes is always a good idea :)
