How to set an VNC Server on Ubuntu 20.04?

Hello, friends. In this post, you will learn how to set up a VNC server on Ubuntu 20.04

Having a VNC server is a good alternative in these moments where work is being done remotely. Because VNC allows us to have a remote desktop server with which we can do jobs if you were on the computer.

This will be a fairly short tutorial because it is quite simple.

Creating a VNC Server on Ubuntu 20.04

Whether you are using Ubuntu desktop or Ubuntu Server it is convenient to install a lightweight desktop environment to make the connection. In this case, I have chosen XFCE.

Now we can install a VNC server. To do so, open a terminal or run via SSH.

sudo apt install tightvncserver

Once the server is installed, it is necessary to define a password.

vncpasswd
Using password file /home/angelo/.vnc/passwd
 VNC directory /home/angelo/.vnc does not exist, creating.
 Password: 
 Verify:   
 Would you like to enter a view-only password (y/n)? y
 Password: 
 Verify:

There you can define a password as a view-only password.

Now configure the server so that when it starts it will run the XFCE environment

So, create a configuration file:

nano ~/.vnc/xstartup

And add the following:

!/bin/bash
 xrdb $HOME/.Xresources
 startxfce4 &

Then close the file and give it execution permission

chmod +x ~/.vnc/xstartup

Now you can start the VNC server.

vncserver
New 'X' desktop is ubuntuosradar:1
 Starting applications specified in /home/angelo/.vnc/xstartup
 Log file is /home/angelo/.vnc/ubuntuosradar:1.log

Now if you open a client program, for example, Vinagre and access it through port 5901
