I don't have a systemd system, and my builds are now somewhat old,
but to attempt to get a little closer towards someone with systemd
identifying where the problem lies: What are the ownership and perms
of /dev/tty0 ?
On this (8.4, sysv) machine where I'm writing this, it is owned by
root:tty with perms of 640.
Googling, this sounds like a non-suid Xorg with startx. i.e. the
switch --enable-install-setuid has been omitted. Ah, I think that
might have been briefly removed after the elogind merge (not sure),
but it is certainly in the current book for both sysv and systemd.
From one of my google results, with some video drivers (including
your intel, but not modesetting!) non-suid X works in destop
environments but not with startx.
--enable-install-setuid was removed again, but I cannot confirm that it
works. We still need to sort that out. For now the easy way is to
sudo -E chmod u+s $XORG_PREFIX/libexec/Xorg
