If you have noticed, when you step away from your Ubuntu desktop for a short while it will automatically lock the screen to prevent others from accessing your files or programs. This is a great feature that is included for security reasons to prevent unauthorized access. Since Ubuntu 20.04 LTS is a test server, it becomes annoying to me as it continues to automatically lock. PLEASE do not do this to your production server. On how to disable screen lock on Windows, see the following guides. How to disable Lock Screen on Windows 10 via Local Group Policy Editor, and how to disable Lock Screen on Windows 10 via Registry Editor, and how to remove your login password from the Sign-in Screen (lock screen) and re-enable Sign-in Screen.
For a more extensive article on how this can be done on Ubuntu 16.04 LTS and how this can be achived using the dconf Editor, please refer to the following guide."Disable blank screen: How to disable automatic screen lock on Ubuntu Desktop with the GUI and dconf Editor"
