How to configure VNC server to get full Gnome desktop?

Few people know this, but Ubuntu already comes with everything you need.

Just search in the menus:

• Vino: this is the server application; there is a configuration UI that lets you configure. Use this in your desktop computer.
• Remmina: the client. If your client is not Ubuntu, you have to use some other application. Remmina is very cool because you can setup tunnels and etc directly.

Notice this comes installed only for Ubuntu proper. For XUbuntu or other distributions, you will need to install these tools. Also, Vino may not work in Wayland -- I would use 16.04 or 18.04.
