[X2Go-User] Running application for multiple users

[Peter Schulz]

I have set up x2go on an Ubuntu 14.04 machine, and it connects and 
creates a new session fine.
However, when I have the first session running an application like 
Firefox or Thunderbird, then have
a 2nd user log in, the 2nd user cannot run Firefox. He gets a message 
"Firefox is already running".

I thought I can connect with multiple users to the same host?
It would not be useful if I can only have one connection. Or do I need a 
session broker for that?
