We are trying to set up a virtual development / research cloud environment for our students. Students need to be able to log-in, launch python IDE, and plot some graphs for their homework.
We are running 64bit Ubuntu 12.10, with Python and IDLE ide installed. Students login with using ssh -X and launch IDLE, which spawns a GUI window.
Problem: running something like this in the ide
spawns a new window. BUT when we try something like this:
Nothing happens, where we would expect a new window to spawn and show the plot (thats what happens on the local machine). I suspect this has something to do with X11 but at this point I am way out of my depth of sys admin knowledge. Confirmed this both from a Mac (xQuartz) and PC (xming) client. Any help would be much appreciated.
