Doing a "sudo" or "su" to run things as the root user can also clear
your individual user X settings, as can using ssh to access the local
system as a root user if you do not allow X forwarding.

Personally, I tend to run as a user, then "ssh -l root localhost" with
my SSH settings and keys set to permit my SSH user on localhost to
connect with ssh-agent and X11 forwarding enabled.
