If we don’t perform this step then all we will see is a grey cross-hatched screen with an “X” cursor and/or a grey screen with a Terminal Session, depending on the Ubuntu version. We now need to kill the session we just created and make a tweak to the startup script for VNCServer to make it work properly. Once you’ve entered it you’ll see the following screen: You’ll then be prompted to create and verify a new password.
This will install VNC Server which is required for running the virtual desktop on the server. Now we’ve installed the components for the desktop we need to install VNC to be able to interact with it. cpu utilisation graphs) Install a Virtual Desktop using VNC This will install the basic xfce desktop components plus a few useful extras (eg. So type the following command (or copy it!): There are plenty of desktop flavours but XFCE is perhaps one of the lighter and more popular flavours so we will go for that one. The command you’ve just copied from here will be automatically pasted into your Putty Session. Then toggle over to your Putty Session and right-click once more. TIP: If you’re going to be following this guide step by step using Putty then you can save yourself some typing by simply highlighting each command below, right-clicking on it and selecting Copy.
Ubuntu tends to prompt for a password each time you issue a “sudo” command. This is the password you created when you installed Ubuntu. To perform the installation of VNC you can either type the following commands into a Putty session or, if you’ve got a screen and keyboard attached to your server, then you can use the command line itself. NOTE: If you’re jumping into this guide here then it’s worth mentioning that this guide has been also tested on Focal Fossa 20.04LTS, Xenial Xerus 16.04LTS, Quantal Quetzal 12.10, Precise Pangolin 12.04LTS, Lucid Lynx 10.04LTS, Karmic Koala 9.10, 9.04 Jaunty, and 8.10 Intrepid. VNC provides a “virtual desktop” so it is more lightweight than a full blown desktop installation. There is a better way however, and that is to install VNC. As a result many people actually install Ubuntu Desktop instead of installing Ubuntu Server since the desktop version of Ubuntu has the GUI built in. Some people find this prospect rather too daunting and would rather use a graphical user interface (GUI) instead.
Putty gives you a “Command Line” interface and so you’ll need to learn a few Linux commands in order to be able to administer your server this way. Once you’ve installed Ubuntu Server you will need a mechanism to be able to administer it. Administer Ubuntu Server Focal Fossa 20.04LTS using VNC
