I tried to install xquartz but gave up half way, so i'm trying to remove it and go back to X11. I followed all the instructions here: http://xquartz.macosforge.org/trac/wiki/X11-UsersFAQ
But i think its not properly done, because when i try to start wireshark (which uses X), i get the following error:
(wireshark-bin:846): Gtk-WARNING **: cannot open display:
Can someone help explain how i can ensure X11 is all set up right?
