如何以较小的值增加/减少亮度？

有没有办法可以在 Linux Mint 上以较小的百分比值（例如 1% 或 2%）而不是 5% 来降低或提高显示器亮度？另外，我也希望修复与我的功能键一起使用的问题。Fn+ F5（亮度降低）和Fn+ F6（亮度增加）。

这是我的inxi -Fxzr报告——

我尝试过以下解决方法 -

  1. ddutil无法像我在笔记本电脑上一样工作。
  2. 亮度控制器应用，但是非常不方便，并且不能与功能键配合使用。
  3. 亮度和伽玛小程序，降低亮度效果很好，但增加亮度就会出现问题。所以也不得不放弃这个。

我还在 linux-mint 论坛以及 r/linux4noobs 和 r/linuxmint 等 subreddits 上交叉发布了这个问题
