As my example showed, you must invoke X apps when su'ed as
HOME=/home/ken xappname
So it can find the Xauthority.
(There are other, more advanced, ways of passing xauth tokens around.
When you have some spare time someday, type 'man xauth' and marvel at how
much more complicated X is than most people realise).
Another approach is to use ssh root@localhost as an alternative to su, if
you have X forwarding enabled in ssh/. This is kind of sucky, and CPU
intensive, but fun (and generalises to non-root users, which the HOME
method doesn't).
