  <title>Tại sao màn hình mờ sau một khoảng thời gian?</title>

  <p>If it is possible to set the brightness of your screen, it will dim when
  the computer is idle in order to save power. When you start using the
  computer again, the screen will brighten.</p>

  <p>You can stop the screen from dimming itself:</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui>
      overview and start typing <gui>Power</gui>.</p>
    </item>
    <item>
      <p>Click <gui>Power</gui> to open the panel.</p>
    </item>
    <item>
      <p>Switch <gui>Blank screen</gui> to <gui>OFF</gui> in the <gui>Power
      Saving</gui> section.</p>
    </item>
  </steps>
