RE: su in X
When you log in as a regular user, and you 'su -' to root, you have to
define you 'export DISPLAY=:0.0' again. The minus sign after the su command
means that you want to assume root's environment. So if there is not an
explicit export DISPLAY statement in /root/.bash_profile or /root/.bashrc,
the root environment has no idea what the display should be.
Hope this helps -mk
