With the latest release of xorg the SUID wrapper for Xorg is now gone /usr/bin/X is just a symlink to Xorg and the /etc/X11/Xwrapper.config is ignored.
This is yet another attempt to shovel systemd down on our throats so even if you avoid systemd as PID 1 at least you need a fully privileged daemon systemd-logind. A quick fix to still avoid the systemd plague is to make either the xinit or Xorg SUID root but this is now equivalent to allowed_users=anybody in the old Xwrapper.config -- Regards, Emil -- Good judgment comes from experience.
