Well it looks like I have a bit more to learn?
At work I tend to log in as root then do su <username>,
the env vars etc. are set by the users .profile .login.
To run any X, testing things etc, on my PC I have to
manually reset DISPLAY to be my PC name and not the users.
This is because we have hostname of two parts <site_id><pc number>.
I think it would still be required to force DISPLAY after
doing su.
