X11 is the GUI-display protocol used by UNIX systems. If you're logging into one of the Nevis systems with your own computer (laptop or desktop) using a plain-text Terminal program, you will almost certainly need X11 to run applications such as ROOT.

Setting up X11 on Linux

It's already there. Note that you can set up X11 forwarding the same way as described for Mac OS.

Setting up X11 on Microsoft Windows
