Wireshark-users: [Wireshark-users] Gtk-WARNING **: cannot open display:

My google searching discovers this is pervasive. None the less, I can't
seem to solve it on my system.

If I type: sudo wireshark in Terminal (and give password) then I get:

(wireshark:528): Gtk-WARNING **: cannot open display:

If I navigate waaaaay down the tree in

and double click the unix executable Wireshark, then it runs but
obviously hasn't the ability to find the network points.

One time, shortly after re-installing X-11 this morning, I was able to
do a sudo wireshark and have it run corectly AND locate the various
network points.

When I discovered that none of my running programs could get to the
Internet anymore, I suspected Wireshark had intercepted the en1 path and
thus I re-booted ... all worked fine except I no longer can run wireshark.

Would some kind soul guide me back to success?

thanks ...
