Fedora 32 上的亮度只能降低/提高 1 级

Fedora 32 上的亮度只能降低/提高 1 级

首先,我不得不说我对 Linux 和 Fedora 完全陌生。因此,如果您需要更多详细信息,请告诉我所需的步骤。

问题是这样的: 我处于最大亮度,然后将其降低 1 级 是的,它变暗了,但是如果我尝试再次降低亮度,它就不起作用 动画播放,但亮度保持不变 如果再次增加亮度,只会在最后一级更亮

如果你还是不明白的话,这里有一个视频https://uploadir.com/u/ifm5dm09

我搜索了“Fedora 32 无法更改亮度”并尝试了必须编辑etc/default/grub.但这只会让情况变得更糟,此后亮度无法更改(但我撤消了更改)。

编辑 1:如果我启动到 Windows,重新启动,然后启动到 Fedora,亮度就会起作用!但是如果我直接启动到 Fedora,就会出现问题

我不知道为什么。我将首先按照评论中的说明尝试升级内核。

答案1

我将内核升级到 5.8 后它就可以工作了,
