Once I needed to use a Chrome extension on my VPS. So I had two options, buy a Windows VPS or install a desktop environment on a linux VPS. I chose the second options as it costs less. At that time, I though that installing a VNC with a desktop environment on a VPS is a tough task. But it wasn’t. It’s really simple.
What is VNC?
Virtual Network Computing (VNC) is a graphical desktop sharing system. It allows one computer to control another computer remotely through mouse and keyword, what we usually do. Windows VPSs comes with RDP which allows us to do this out of the box. But Linux VPSs does come with any graphical desktop sharing system. That’s why we need to install a VNC.
Install VNC and GUI
Before installing a VNC, we need to setup a graphical user interface in the VPS. There are many popular GUIs like; GNOME, KDE Plasma and Xfce. In this guide I am using GNOME as the Desktop environment.
First, we need to update our VPS.
sudo apt-get update && sudo apt-get upgrade -y
Then we have to install the GNOME.
sudo apt-get install ubuntu-desktop gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal
Let’s install a VNC server. I am going to use vnc4server in this guide
sudo apt-get install vnc4server
To start a session in VNC server,
:1 means the port. So your VNC server is running at YOUR_SERVER_IP:1. The first time when this command gets executed, it requires you to put a password. You can give any password. Now you should able to connect to the VNC server through a VNC client software like realVNC Viewer which is available on almost every platform; macOS, Windows, Android and iOS.

Is the job done? No, not yet. If you got a grey background, don’t worry.
First, kill the VNC session.
vncserver -kill :1
Then we have to edit the ~/.vnc/xstartup file. Open this file using any text editor you prefer, I am using nano; my favourite.
Please note that you need to start a VNC session at least once to create this file.
Now replace the whole file with following lines.
#!/bin/sh # Uncomment the following two lines for normal desktop: # unset SESSION_MANAGER # exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & x-window-manager & gnome-panel & gnome-settings-daemon & metacity & nautilus &
Then save the file. Press ctrl+x, then y and then enter, to save the file. So we have done the GUI configuration part.
Next, start the VNC server.
Then again connect to the VNC server through a VNC client software like realVNC Viewer.
