I found the tutorial on setting up x2go on Ubuntu to be very detailed and well-laid out, with substantive screenshots and a thorough process. http://www.howtoforge.com/how-to-install-x2goserver-on-ubuntu-14.04-as-vnc-alternative However, when trying to connect from one Ubuntu Studio 14.04 to another (xfce4 desktops), the client attempting to connect simply timed out. The server task manager shows the x2gocleansessions process running all the time. When the client access is attempted, an x2go sqlitewrapper starts up. An x2gosession then starts up, but then disappears. an x2go sqlitewrapper starts up again, then disappears, and the client then times out. I don't see anything in the var/log/auth.log at that time. Are there some other prerequisites that must be accomplished before this, such as SSH client and server configuring?
