Hi, when trying to run an X11 program, I get the following error message: (putty:8198): Gtk-WARNING **: 00:06:49.190: cannot open display: :0
Which means that your environment has the DISPLAY variable set to ":0" which indicates the first display on the local physical machine, or at least it would on most platforms that support X11. On a Mac, it's much more complicated and your DISPLAY should be a pathname to a socket in a subdirectory of /private/tmp/, whose use triggers the startup of the X display server and window manager (/Applications/MacPorts/X11.app.)
How can I fix that?
Make sure you have the xinit port installed (you should, as the xorg-server port depends on it.) Also make sure you have logged out and back in after installing xorg-server (and its dependencies like xinit.)
