systemd service file for running a vncserver (e.g. tightvncserver)
# Vncserver service file for Debian or Ubuntu with systemd
#
# Install vncserver and tools
# e.g. apt-get install tightvncserver autocutsel gksu
#
# 1. Copy this file to /etc/systemd/system/vncserver@:1.service
# 2. Edit User=
# e.g "User=paul"
# 3. Edit the vncserver parameters appropriately in the ExecStart= line!
# e.g. the -localhost option only allows connections from localhost (or via ssh tunnels)
# 4. Run `systemctl daemon-reload`
# 5. Run `systemctl enable vncserver@:<display>.service`

Perhaps your VNC server service file setting is incorrect, but I have no experience and available time to test the VNC server with Gnome desktop.

I understand, thank you. It seems like VNC isn't yet a plug&play technology... I can't find how to make VNC working through SSH on Ubuntu 20.04 that launch automatically on startup. Never mind, I'll give xrdp a try.

I am trying to use the file on Raspbian x86 in a virtual machine under VMware (whicn doesn't have RealVNC installed in the image, or for free). It seems like it's starting, but I can't connect to it. Here's the status, when I run vnc@:1.service:

Any Idea why I can't connect on 5900, 5901, 5800 or 5801?
