I have not been able to get x2go server/client to work on Ubuntu 12.04 client/server machines.

I installed the x2go ppa for ubuntu

    sudo add-apt-repository ppa:x2go/stable

I installed on the server the x2goserver:

    sudo apt-get install x2goserver

on the client I installed the x2goclient:
   
    sudo apt-get install x2goclient

On ubuntu 12.04 I have installed the 'fallback' gnome desktop support but in previous versions both Unity or gnome worked.

Now when attempting to start an x2go client session (see below):

ssh connection gets established
public/private keypair are generated
search for proxy starts
session aborts/terminates

Anyone got any ideas what the problem might be or how I can troubleshoot further?
