Noted.

What you describe doesn't make much sense to me either.
In this case, there are no user logins on the console, this is meant to be a remote login server. Anyone logging in via vnc gets the black screen treatment. There is no login screen, only the vnc password prompt.
For this type of machine, multi-user.target should be sufficient, although it is set to graphical.target right now.
