To get the device permissions right startx can only "upgrade" a text
session to a graphical one, it cannot open a new VT. Hence if you want X
to show up on session N, then you need to start it from ttyN... Note
that only tty1-6 get logins by default, but you can configure that with
NAutoVTs= in /etc/systemd/logind.conf.
