Does this VNC server act as its own X display, or does it screen-scrape 
what's shown on your regular monitor and serve that over VNC? If the 
latter, you want to start VNC after you've logged in, not at boot.

You may need to enable "user linger" for that username, so that systemd 
doesn't kill any processes running as that user once you've logged out. 
I'm not sure if this is only required for processes started by 
cron/similar, or also processes launches by systemd.
