How I got it working

Prerequisites: you need a working ssh server on your Fedora 20 box and port 22 forwarded from your internet router to the Fedora 20 PC.

yum install x2goserver

Gnome 3 doesn't seem to work I tried gnome-session --session=gnome-fallback to no avail. So installed MATE and it ran well

yum groups install "MATE Desktop"

If you are using Windows to connect to our remote x2go server download the x2go Windows client from http://code.x2go.org/releases/

Configure your client to use a custom session of 'mate-session'

X2GO is well worth getting running. I am finding it works very well. (RDP or ICA well).

If you are trying to get out of Full-Screen mode use the "Windows Key" (worked for me)

or if you are using the Linux client I found a magic pixel at the very top right of the screen. Just take your mouse to the very top right corner and click and you will exit full screen.
