====== X2Go ======
 

''X2Go'' enables users to access a graphical desktop over low or high bandwidth connections. It provides a remote desktop solution tunneled over ''SSH'' supporting file and printer sharing.

We recommend that users install the latest version of ''X2Go'' by downloading it from https://wiki.x2go.org/

<note warning>
For Microsoft Windows users\\ there is a BUG with the lastest x2go client version.
Please the older versions. For example : https://code.x2go.org/releases/binary-win32/x2goclient/releases/4.1.0.0-2017.03.11/
