<title>为什么我的屏幕过一会就变暗？</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>To 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 the <gui>Dim Screen When Inactive</gui> switch to off in the
<gui>Power Saving</gui> section.</p>
