Back in the terminal, run the below command to allow the VNC port number 5900 in the UFW firewall.Close the Media Sharing window and the Settings app.Remote Desktop should now be On, and Media Sharing is now Active.Change the password or keep the default and copy it.Next, ensure that the Sharing toggle is on.Open the Settings app and click Sharing on the left-hand side.Now that you’ve ensured you have the latest Vino VNC let’s start enabling the Ubuntu screen sharing feature. I am using port-forwarding to my SSH servers also.Install the Vino VNC server package.

When I am finding instructions about this on the internet, the instructions are typically configured with SSH post 22 on a LAN, but not with port-forwardings to several machines and servers like I and many others prefer. I have tried several VNC servers with complete reinstallation, for avoiding conflicts, but right now I have installed xfce4 with TightVNC Server. Gconftool-2 -set -type=int /desktop/gnome/remote_access/alternative_port sudo lsof -i -P -n | grep LISTEN Updated after answer from have tried following without being able to change the listening port: gconftool-2 -set -type=bool /desktop/gnome/remote_access/use_alternative_port true Now I have installed a new Dell EMC server with Ubuntu 22.04 LTS server, and it looks like I cannot use the dconf-editor to open the listening ports for VNC-server, at least I cant find the port under org>gnome>desktop>remote-access after installing dconf-editor. We are using TightVNC for windows clients. The router is set up with port-forwarding to the different IP addresses. The ports are of course open in the firewall. I have used dconf-editor to make the listening ports for VNC. I have until now been running on Ubuntu servers 20.04 and lower, where I have used headless server settings, with SSH access, with specific ports for each server for terminal commands, and VNC with specific ports for remote desktop.
