How to Change Screen Timeout in Ubuntu Linux
Changing your Ubuntu Linux screen timeout involves adjusting the Blank Screen Delay setting within the Power settings.
This Blank Screen Delay is the time your Ubuntu computer waits before the screen dims and turns off due to no activity.
By default, this timeout is set to 5 minutes, which might feel too short if you frequently step away from your computer. This setting helps save power and keeps your screen private when you’re not using it.
You can easily set a longer timeout to match how you use your PC, so your screen stays on for as long as you need.
Adjust the Blank Screen Delay in System Settings under Privacy or Power. Navigate to Settings, then Privacy, and select Screen to find the Blank Screen Delay drop-down. You can also access this via Settings, then Power, and adjust the Screen Blank option.
How to change when your computer screen goes blank in Ubuntu Linux
You can easily change how long your Ubuntu screen stays on before it goes blank. This setting, known as the screen blank delay, helps save power by dimming your display after a time of no activity. Adjusting this setting is possible using Ubuntu’s System Settings.
Ubuntu Linux centralizes most of its settings. You can manage everything from system configurations to user creation and updates within the System Settings panel.

On the System menu, select Settings (it’s highlighted in the image 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.


The Blank Screen Delay can be adjusted independently of the Automatic Screen Lock in Ubuntu Linux.
And that’s it! You can now close the Settings app.
