How to Change Screen Timeout in Ubuntu Linux

This post describes steps to change the time when the Screen goes blank in Ubuntu Linux.

Ubuntu Linux comes with a Blank Screen Delay feature that controls the period of inactivity, after which the Screen will go blank.

Blank Screen Delay and Automatic Screen Lock are set for 5 minutes by default. So after 5 minutes of inactivity, your Ubuntu Linux screen goes blank and locks itself.

Automatic Screen Lock is a security feature that ensures no one can sign into your computer while away, thus protecting your data. Blank Screen Delay enhances your privacy so no one can view your desktop while you are away.

Blank Screen Delay is also used to save energy, lower your power bills, or extend your device’s battery life.

Below is how to change Blank Screen Delay in Ubuntu Linux.

Ubuntu Linux has a centralized location for the majority of its settings. From system configurations to creating new users and updating, all can be done from the System Settings panel.

Alternatively, click on the System menu at the top-right corner of the top bar on your desktop.

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

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

In the System Settings -> Privacy settings pane, click on Screen to open the panel.

In the System Settings -> Privacy -> Screen settings pane, use the Blank Screen Delay drop-down list under Screen Lock to set the time until the screen blanks or disable the blanking altogether.

Alternatively, go to System Settings -> Power to open the penal. Then use the Screen Blank drop-down list under Power Saving Options to set the time until the screen blanks or disable the blanking altogether.

You can set the Blank Screen Delay independently of Automatic Screen Lock in Ubuntu Linux.

That should do it. You can now close the Settings app.
