I have started ssh with the command user@server -x, and connect just fine, then when I try to run an X application I get this error
Error: Can't open display:
If I try to run a Gtk application I get this error
Gtk-WARNING **: cannot open display:
Am I doing something wrong? I was told that I should just be able to start ssh with the -x flag then it would take care of the rest. I think the problem could be our firewall, but I don't know what port to open up.
