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.

  • You used to be able to drop to a command line and run startx :1 to start a second session. – Mordoc Aug 23 '13 at 17:52
  • @Mordoc, I found I can start a new xsession over ssh using startx -- :1, though I still couldn't figure out how to forward GUI applications. – Rucent88 Aug 27 '13 at 14:56

As an alternative solution to your problem, you can reuse the existing display :0 for running applications.

DISPLAY=:0 ssh -X username@192.168.0.100
