Hi Rob,

By default, Devuan uses the seventh tty for X sessions. The permision is
denied because xserver-xorg is not SUID root. If it is called from
another SUID root program (a display manager like slim or lightdm) it
will work. But first, you can try reinstalling xserver-xorg package to
set the correct permissions, once created the user.

Cheers,

Aitor.
