For this particular post, we will install the XFCE desktop environment. It is fast, stable, and easy to use. XFCE is very popular and lightweight. You can also install multiple desktop environments at the same time, and just switch between them. However , you may end up with bugs or conflicts, depending on the desktop environments you have simultaneously installed.

After establishing an SSH connection to your server, execute the following command to update your package index:. You will see a prompt to select a display manager for your newly installed XFCE Desktop Environment during the installation. There are several VNC servers available for Linux today. For this particular tutorial, we will install the TigerVNC server.

Execute the command below to initialize the VNC server instance and set up a password. Assuming you are acting as a non-root sudo user , do NOT execute this command with sudo :. After setting up the password, you will get a prompt to set a View-Only password. I will just type N and hit Enter. We can see this process lists the connection information for our VNC server from the message above. Additionally, it started the VNC server at port , which is the display port.

This port is referred to as If you create additional VNC server instances, they will be presented as port as :2 , port as :3 , and so on. Up to this point, our VNC server is up and running. Now we need to configure the commands that will be executed by the server every time we start a VNCV instance. Execute the command below:. If another instance were running on another port, say or , we would execute the commands vcnserver -kill :2 and vncserver -kill :3 , respectively.

To configure VNC, we will need to create a file called xstartup file in the. Execute the commands below:. By default, TigerVNC accepts connection only from In my case, I will use From the image above, you can now see our VNC server is well configured, and we can access it from our local machine. To establish a secure connection, restart your VNC server by simply running vncserver without the -localhost no option as shown below.

That ensures that the VNC server only accepts connections incoming from the server where it is installed. To get around this and connect to the VNC server from our local machine, we will establish an SSH tunnel from our local machine to the server. That is also an additional layer of security as only users with SSH access to the server can connect to the VNC server. You can choose whichever one you prefer. On Windows you can use PowerShell or a terminal emulator such as Cmder.

In my case, I will execute the command below:. Alternatively; you can add a -f argument which runs SSH tunneling in the background. Now to connect securely to your VNC server, launch the VNC client application and connect with the address localhost :. If you are connecting to your server using Putty, create an SSH tunnel using the procedure below. On the left side of the Putty window, scroll down and get to the SSH option. Extend it and select the Tunnels option. Enter the details as shown in the image below—Port as the source port and localhost as the destination address.

We will also use systemd to launch our VNC server on boot. With that done, we can now start, stop and restart our VNC server as a system service. You have successfully installed and configured the VNC server on Ubuntu Please keep in mind that if you install multiple desktop environments on the same machine, then you may encounter bugs or conflicts, depending on which you have installed. We covered this initially in the tutorial, but will add it here too, so the article is more easily skimmable.

Now restart the VNC server and next time you connect you should be using Budgie. Now restart the VNC server and next time you connect you should be using Cinnamon. I believe this guide has given you a step-by-step guide on installing and configuring a VNC server on Ubuntu Feel free to share any additional VNC configuration tips with our readers or ask any questions in the comments below or by contacting us. U Ubuntu. Not using Ubuntu? Choose a different version or distro.

For a somewhat different take on remote desktops you can also check our tutorial on Xpra. A Display Manager is a program that enables your Linux distribution to possess graphical login capabilities. If you're not sure of the name of the machine to which you've connected, use the hostname command:. Set a VNC password by running vncpasswd at the command prompt. Note that VNC passwords must be 8 characters or less - if you type a longer password, everything after character eight is ignored.

Technically you don't need to set up a new VNC password if you've previously created one, but doing this each time ensures you remember what it is! Note that while you're typing your password on Linux, you will not see any feedback at all no asterisks. After pressing the Connect button, you will be asked for two passwords.

There may be somewhat of a delay, but after all this you should soon see a new VNC window containing a Linux desktop session. If you see a blank window, be patient for a bit - but if it continues to be blank, end the current session and try starting over again using a different Linux Lab machine - the one you chose may already be bogged down with too many other users. From the command line on the remote machine, use the vncserver -list command to determine the display number of your VNC session.

Then, run vncserver -kill to quit any sessions which need not remain open note that you do not add in this case - use the exact display number reported. Close any VNC sessions as in the previous section, then delete the vnc password file. This will wipe out any saved password for the VNC session:. Note: things will be more complicated if you have started VNC server sessions on multiple hosts.
