Hi, thanks for your reply. So would this be a second instance of the X server used for DISPLAY :1 ?
At the moment my machine boots up in console mode, and I have an upstart script which launches XBMC via xinit. So the X server is started just for the XBMC process. To start a DM in DISPLAY :1 would this also be done via xinit, or can I somehow re-use the same X session that was spawned for XBMC?
