you can use also 

  + ssh -X {container}

  + or this more complex solution including sound:
     
        https://www.stgraber.org/2014/02/09/lxc-1-0-gui-in-containers/

  + work with xauth:

     - on the host use

         xauth list

       and extract the key, copy it starting with unix:
 
     - in the container

          export DISPLAY=unix:0.0
	  xauth add {key from host, starting with unix:}

   + any other solution, like VNC or NX, but then you get usually the
     whole desktop. And I guess, you are only interested in only one
     application...

And all these work even with unprivileged containers.
