I hope you don't mind me CC users at autonlab since this is not the first nor
the last e-mail I will receive this holiday season with the same question.

You can't neither Gnome nor KDE are installed on any of computing nodes.
You can lunch a single application xterm which will in turn allow you to
lunch MATLAB for example in GUI mode or RDesktop. The other option is
custom desktop using JWM (Joe's own window manager). I think
I installed few other window managers but JWM is the easiest to use.

Please just use bash.autonlab.org as a proxy to access computing node and
forget about port forwarding. bash.autonlab.org might become unavailable
when I use it to connect to NREC. I am almost done with NREC so it will be
at most couple of hours next couple of days.
