  <title>自动锁定屏幕</title>
  
  <p>When you leave your computer, you should
  <link xref="shell-exit#lock-screen">lock the screen</link> to prevent
  other people from using your desktop and accessing your files. If you
  sometimes forget to lock your screen, you may wish to have your computer’s
  screen lock automatically after a set period of time. This will help to
  secure your computer when you aren’t using it.</p>

  <note><p>When your screen is locked, your applications and system processes
  will continue to run, but you will need to enter your password to begin using
  them again.</p></note>
  
  <steps>
    <title>To set the length of time before your screen locks
    automatically:</title>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Privacy</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Privacy</gui> to open the panel.</p>
    </item>
    <item>
      <p>Select <gui>Screen Lock</gui>.</p>
    </item>
    <item>
      <p>Make sure <gui>Automatic Screen Lock</gui> is switched <gui>ON</gui>,
      then select a length of time from the drop-down list.</p>
    </item>
  </steps>

  <note style="tip">
    <p>Applications can present notifications to you that are still displayed
    on your lock screen. This is convenient, for example, to see if you have
    any email without unlocking your screen. If you’re concerned about other
    people seeing these notifications, switch <gui>Show Notifications</gui>
    off.</p>
  </note>

  <p>When your screen is locked, and you want to unlock it, press
  <key>Esc</key>, or swipe up from the bottom of the screen with your mouse.
  Then enter your password, and press <key>Enter</key> or click
  <gui>Unlock</gui>. Alternatively, just start typing your password and the
  lock curtain will be automatically raised as you type.</p>
