Vino was a VNC server for the GNOME desktop environment, the GNOME developers now recommend using "gnome-remote-desktop" instead.
Configuration up to version 3.8.0 was via the vino-preferences program. This was removed from the packages after that version, since the gnome-control-center could then be used alternatively to control settings.
However, Vino is also useful in some other Linux distributions, which may not use GNOME desktop; and where gnome-control-center is not present: this leaves those distributions with no preference editor. For these distributions, (Lubuntu is one example, being based on LXDE, not GNOME), the alternative configuration manager tool dconf-editor is recommended (sudo apt install dconf-editor to install). The VNC settings can then be accessed under org -> gnome -> desktop -> remote-access using that tool.
