How to Enable Automatic Screen Lock in Ubuntu Linux

You enable automatic screen lock in Ubuntu Linux to secure your system when you’re away.

Automatic screen lock is a vital security feature that locks your user session after a set period of inactivity, requiring your password for re-access.

This protects your sensitive data and running applications from unauthorized use.

For example, the default GNOME desktop environment in Ubuntu 22.04 LTS allows you to configure this timeout, with a common default setting of 5 minutes.

You control exactly how long Ubuntu waits before automatically locking your screen.

How to turn on or off automatic screen lock in Ubuntu Linux

It’s always recommended to lock your computer screen when you are away to prevent other people from using your desktop and accessing your files.

Ubuntu Linux automatically locks the screen when there’s no active user activity. This protects your desktop and files from unauthorized access.

Here’s how to turn it on or off in Ubuntu Linux.

Ubuntu Linux has a centralized location for most of its settings. You can manage system configurations, create new users, update the system, and more from the System Settings panel.

To open System Settings, go to the Activities overview (where you can search for applications) and type Settings.

Alternatively, click the System menu (usually found in the top-right corner of your desktop’s top bar).

On the System menu, select Settings, as highlighted below.

In the Settings app, click the Privacy tile to expand it.

In the Privacy settings, click on Screen to open that panel.

In the Screen settings, toggle the Automatic Screen Lock switch to On or Off.

If you are turning it on, select a length of time from the Automatic Screen Lock Delay drop-down list before the screen locks. If turned off, that option will be grayed out.

When your screen is locked and you want to unlock it, press the Esc key or swipe up from the bottom of the screen with your mouse.

Enter your password and resume your session.

That should do it!
