<title>设置屏幕亮度</title>
<p>取决于您的硬件，您可以通过调节屏幕亮度来节省电力或使其在强光下更容易阅读。</p>
<p>要改变屏幕亮度，请点击顶栏右侧<gui xref="shell-introduction#systemmenu">系统菜单</gui>并调整屏幕亮度滑块到您想要的值。此更改应能立即生效。</p>
<note style="tip">
<p>很多笔记本电脑的键盘上有特殊的功能键可以调整亮度。这些键上带有类似太阳的图标。按住 <key>Fn</key> 键来使用这些功能键。</p>
</note>
<note style="tip">
<p>如果您的计算机集成了光线传感器，屏幕亮度将会自动调整。详情参见<link xref="power-autobrightness"/>。</p>
</note>
<p>如果屏幕亮度可以调节，也可以设置让屏幕自动变暗以省电。有关更多信息，请参阅<link xref="power-whydim"/>。</p>
