At University and on my home computer, I use a program called PuTTY to SSH connect to (a linux server), and I use the program Xming to display visible elements, such as java and python GUIs and the like.

Basically I'm wondering what the process is to do this with XQuartz. When I try I get told I have no Display variable set, and I've googled for a while but I can't find a solution (most things also talk about X11, but I'm on Mountain Lion so the replacement is XQuartz).

This problem was solved on Windows by introducing Xming, so is there such a solution on Mac?

Thank you in advance!

If I remember correctly, you need to do:

$ ssh -X user@servername

And maybe this before the SSH:

$ xhost + servername

From the SSH man page

-X      Enables X11 forwarding.  This can also be specified on a per-host
         basis in a configuration file.

Thank you for your quick response, but I've tried both of those in the past. I believe -x enables X11 forwarding, but there's nothing that will actually display it (I had the same problem on Windows, with nothing to display the GUI, until I installed and ran Xming before hand which now handles showing the GUI). – Jamie Dec 26 '12 at 20:24
-x Disables X11 forwarding. X (uppercase, activates it). If you run those from X11 (or XQuartz) this should works. – Michel Guillet Dec 26 '12 at 20:29
Ah, I did not realise there was a difference between the two. Thank you very much! Such a simple mistake. I feel quite silly with my previous comment now aha, thank you so much. – Jamie Dec 26 '12 at 20:32
=) did it work? – Michel Guillet Dec 26 '12 at 20:45
