I want to forward an Xsession over ssh to another system, but I get this error:
Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again.
I don't want to kill the currently running Xsession. How can I start a new Xsession for ssh forwarding?
Running Ubuntu 12.04 on both client and server.
