Sudo reboot Step 2: Install Desktop Environment on Ubuntuĭesktop Environments are usually not included with a server edition. Run the following command to update Ubuntu system. The following steps will guide on how to install RealVNC server on Ubuntu 22.04|20.04|18.04.
RealVNC architecture: Install RealVNC Server on Ubuntu 22.04|20.04|18.04 Virtualisation design simply provides another layer of abstraction, and to achieve low latency across hundreds of concurrent connections per server. In this tutorial we demonstrate how to Configure RealVNC Server and Client on Ubuntu 22.04|20.04|18.04. VNC is a Linux program that allows you to connect in to a Linux server graphically from a remote location. Remote technical help and viewing files on one’s work computer from one’s home computer, or vice versa, are two common applications for this technology. A VNC server can be accessed by multiple clients at the same time. VNC is platform-agnostic, including clients and servers supporting a variety of Graphical User Interface based OS. It relays graphical-screen changes while sending keyboard and mouse input from one machine to another over a network. I use this method when I'm on an unstrusted connection (in both way) through SSH tunnel and it works like a charm.Virtual Network Computing acronym VNC is a graphical desktop-sharing system that employs the Remote Frame Buffer protocol that is RFB to control second remote computer in computer technology. For example :ĭISPLAY=:99 export $DISPLAY Xvfb $DISPLAY & openbox & # Or whatever DE/app you want x11vnc -display $DISPLAY # Or whatever VNC server you want, this one terminate with the connection it handle What you can do, if none of the way above is possible, is start a headless X session (with Xvfb) on which you can attach VNC from SSH and even start a desktop environment from here. You can't usually start VNC remotely on a user session because of X default security policies (check xhost). Start your session then launch a VNC server (which can be automated in DE's startup scripts, but you'll have to handle multiple ports through memory if you need to handle multiple user sessions) Use a greeter that support the use of a VNC server to login remotely (I don't think this exists, they usually use VNC through XDMCP which may not be what you want because you need an X client to connect)
VNC servers needs to be attached to a graphical session so you need to either : I don't know what you tried or what your specific use case/requirements are, but by how you tell us, I think you misunderstood what VNC is (by assuming it's an 1:1 Windows RDP replacement) and maybe you should use alternatives as other comments tells you.
