Look, I know the executable is vncserver. The question is how do I get the

handles.
Are you sure you actually *want* to use systemd to start it? It doesn't
really seem like the best choice to me. For one thing, when you start
it from a user's crontab with @reboot, it runs as the correct user
automatically. I don't know how systemd knows which user to start the
VNC session as.
Maybe I just don't understand the concept of a "standalone (VNC) server".
I've got some workstations with tightvncserver installed, and I've got
two sessions running on each workstation, as two separate user accounts.
Each one is started from the user's crontab file, with a customized
resolution for each human user.
That puts an interesting twist on it. I just rebooted and the service
doesn't actually appear to restart. It shows as dead.

However I can run vncviewer localhost:5901 and connect as my user. I'm
seeing a black screen but that's a separate issue, I think.
Strangely, I am now getting a connection from my laptop. So now I just
have to resolve the black screen issue. Apparently the default
configuration requires a strong enough encryption to allow non-local
connections. I'm not sure why I wasn't connecting yesterday, but it's
working now.
As for the user under systemd, I think that is determined by the
connection. There is also a file (/etc/tigervnc/vncserver.users) that
links the connection to the user name. I only need to enable the actual
connection service for each user.
