Wouldn't it be easier to install a VNC server on your Ubuntu and use the Jenkins VNC plugin to manage an X server for use by your build? I use that regularly and it works very well for me on Debian and Red Hat and CentOS machines.
Then you don't need to remember to keep the X server running and you don't need to remember to unlock its permissions.
