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.
