If you pasted the entire error message here, then it looks like the DISPLAY
variable is not set in your environment. Is that the case? Of course, you
could have just left of the display number at the end of the message...
I always try to run a very basic X-Windows command to see if authentication is
working: xclock. If you can't run xclock, then you have either a display
specification problem or an X authentication problem. The first thing is to
make sure DISPLAY is set on your remote system
to "<hostname>:<display>.<screen>", where "<hostname>" is the name of your
local X server system (resolvable from the remote system), and <display> and
<screen> are usually zero.

MacK - No, that's the whole error message. I got the same ideas as you,
but as you can see below, that does not seem to be the case. xclock
works from the non-root user, but not under sudo.
