There was a thread on this recently, so for all the details you
might want to check the mailing list archives.
But basically X clients authenticate themselves by using the
.Xauthority file. So if the user running the X session su's to root,then
the user's .Xauthority file (with the magic cookies) is not found in /root,
and root can't get authorized.
One way is to link roots .Xauthority to the users .Xauthority.
But there are a couple of other suggestions in the archives.
