  <title>Set screen blanking time</title>

  <p>To save power, you can adjust the time before the screen blanks when left
  idle. You can also disable the blanking completely.</p>

  <steps>
    <title>To set the screen blanking time:</title>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Settings</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Settings</gui>.</p>
    </item>
    <item>
      <p>Click <gui>Power</gui> in the sidebar.</p>
    </item>
    <item>
      <p>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.</p>
    </item>
  </steps>
  
  <note style="tip">
    <p>When your computer is left idle, the screen will automatically lock
    itself for security reasons. To change this behavior, see
    <link xref="session-screenlocks" />.</p>
