Running Xorg with suid is insecure and can lead to privilege escalation. So this method of running Xorg is no longer recommended. The systemd-logind and elogind by default only allow you to run X on the console you have logged in as a user - this is controlled by the corresponding pam module (e.g. pam-elogind.so). As I understand it systemd-logind and its elogind derivative both use the variable $XDG_VTNR to set the VT number. I suppose this variable could be set to a different VT than the console you login, via .xinitrc, or .xserverrc, or .bashrc - but I haven't tried it out.
