  <title>Set screen blanking time</title>

  
To save power, you can adjust the time before the screen blanks when left

  idle. You can also disable the blanking completely.

  <steps>

    <title>To set the screen blanking time:</title>

    <item>

      
Open the <gui xref="shell-introduction#activities">Activities</gui>

      overview and start typing <gui>Power</gui>.

    </item>

    <item>

      
Click <gui>Power</gui> to open the panel.

    </item>

    <item>

      
Use the <gui>Blank screen</gui> drop-down list under <gui>Power

      Saving</gui> to set the time until the screen blanks, or disable the blanking

      completely.

    </item>

  </steps>

  <note style="tip">

    
When your computer is left idle, the screen will automatically lock

    itself for security reasons. To change this behavior, see

    <link xref="session-screenlocks"/>.
