Configuration

1. First, you need an X server installed (outside of the scope of this article), or at least some of the libs, to be able to run the apps.
   You also need xauth and maybe xhost (in the package x11-xserver-utils)
2. Second, you need ssh to accept X Forwarding (in /etc/ssh/sshd_config):
   X11Forwarding yes
X11UseLocalhost yes
X11DisplayOffset 10
3. Third, you need a real X server to display the X apps on the client (XMing, Cygwin/X, VcXsrv, etc...)
4. so that you can do export DISPLAY=localhost:10.0 and run X apps
