Since I am on Ubuntu, I'll try to have X11 forwarding through ssh on a remote desktop. But unfortunately it does not work. Before I do this :

ssh -X username@hostname

and then for example :


But now under Ubuntu 15.10 It does not work and I have this message :

$ gedit Failed to connect to **Mir**: Failed to connect to server socket: No files or folders of this type Unable to init server: Unable to connect: Connection refused

(gedit:2492): Gtk-WARNING **: cannot open display:

After restarting the SSH Server everything should works fine.
