How to Change Screen Timeout in Ubuntu Linux
Changing the screen timeout in Ubuntu Linux stops your display from dimming and locking too quickly when you step away from your desk. Ubuntu sets a default five-minute limit to save battery power on laptops and protect your privacy, but this often feels too short when you read long web pages or watch videos.
You can adjust this timer through the standard Settings app in Ubuntu 22.04 and newer versions to keep your screen awake 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
Ubuntu Linux centralizes most of its configuration options. Manage everything from system preferences to user accounts within the System Settings panel.

Click the system menu in the top-right corner of the top bar, then select Settings as shown in the image.
Highlight Settings on the system menu below.

Click the Privacy tile inside the Settings app to expand it.

Open the panel by clicking Screen inside the System Settings -> Privacy settings pane.
Open System Settings -> Privacy -> Screen, then use the Blank Screen Delay drop-down menu to pick a new duration or turn blanking off entirely.

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

Ubuntu Linux allows adjusting the Blank Screen Delay independently of the Automatic Screen Lock.
Close the Settings app once finished.
