So this isn’t so secure so you might need to install something called xscreensaver. So change your settings>privacy>screen lock to the following. OH – A GOTYA – don’t lock the screen as you wont be able to VNC back in. It’s important to check that you can log in from the ‘login’ screen. One last test before calling it done is to reboot the system once again. You can check on the status of this service, like others, using systemctl status rvice. While we’re there we may aswell start the service then test it systemctl start rvice. Super – now we need to tell the systemd system there is a change and to reload systemctl daemon-reload, followed by enabling the new service systemctl enable rvice. we also want the service to be started before the process reaches the multi-user target.the ExecStart and Stop commands should be self explanatory, If you have an existing desktop session running on your linux workstation, you should be able to connect remotely to it with VNC.forking as the x11vnc creates a child process from the -forever clause.start after some other services have been started / target points have been reached,.Sudo nano /lib/systemd/system/rviceĪfter=rvice network.target syslog.targetĮxecStart=/usr/bin/x11vnc -forever -display :0 -auth guess -passwd password (this is insecure but it’s fine for testing on a LAN I guess.) A local PC from which you can install a VNC client (we'll cover options for Windows 10/11, macOs, and Linux below) How to install VNC Server on Ubuntu When you boot your Ubuntu server for the first time, you'll notice there's no GUI. You can skip this step if you like but I would recommend running x11vnc from a terminal and trying to connect remotely. An Ubuntu 20.04 server with a non-root admin user and configured firewall (need one quickly Sign up to BitLaunch).

So why you might want to do this is for remote access via a GUI, or screen sharing, or to a headless server, or virtual machine? Installing x11vnc from the gnome-software centre doesn’t ensure that it starts on boot without a graphical session being logged in each time the machine restarts, hence a slightly longer process is needed.įirst thing we need to do is change the display manager over to lightdm (away from gnome display manager 3).

Hey All – revisiting an old one again here with an update for 20.04 (and also the versions in between (most probably).
