What is VNC and why use it?
VNC is an open-source software that allows users to access their computer remotely, whether it is a desktop or a server.

Troubleshooting VNC on Ubuntu 20.04
As with any software, there may be times when things don’t go as planned while setting up VNC on Ubuntu 20.04. Here are some common issues and their solutions:
1. Connection refused
If you are unable to connect to the VNC server, you may receive a “connection refused” error. This can be due to several reasons, including:
- Incorrect IP address or hostname
- Firewall blocking VNC traffic
- VNC service not running on the server
To resolve this issue, first, make sure that you have the correct IP address or hostname. Then, check your firewall to see if it is blocking VNC traffic and make the necessary changes. Finally, ensure that the VNC service is running on the server.
2. Password authentication failed
If you are unable to connect to the VNC server because of a password authentication failure, it could be due to incorrect password or a typo when entering the password. Double-check the password and make sure that you have entered it correctly.
3. Display resolution issues
If you are experiencing issues with the display resolution, such as it being too small or too large, you can change the resolution by editing the configuration file for the VNC server. Simply open the file with the following command:
nano ~/.vnc/xstartup
And add the following line at the top of the file:
export GEOMETRY="1024x768"
Replace “1024×768” with the desired resolution and save the changes. Then, restart the VNC server for the changes to take effect:
vncserver -kill :1
vncserver
