I'd like to have 2 VT's running, one on VT7 with the standard lightdm + unity interface and another on VT8 running a custom script which will launch a virtual machine in full screen.

At the moment I've tried writing an init.d script with no luck and I can't find any details on a configuration file which will allow me to start 2 servers.

I suppose my ideal answer would be one which points me to a config file I can edit to start up an additional server.

Edit - I forgot to mention in the text that I already know how to start another X session: I'd like this to start automatically at boot.
