我刚刚购买了一台 Gigabyte Aorus 7 SB 笔记本电脑并安装了 Ubuntu 20.10。
这台笔记本电脑配有 RGB 背光键盘。它配备 Windows 10 和一款用于更改背光颜色和亮度的 Windows 应用程序。我试图控制背光键盘，使其变暗或关闭，然后在需要时再次打开它。
当我安装 Ubuntu 时，键盘背光为非常明亮的蓝色。我尝试了一堆 xset led 组合，但它们对 LED 照明没有任何作用。
我尝试使用 xset led off 和各种其他 xset 组合，例如 xset -led 3（以及每个最大为 32 的数字）。
我最终再次启动 Windows，并使用提供的应用程序更改颜色并调暗键盘。但我想从 Ubuntu 内部控制它。
有人成功使用过这台笔记本电脑吗？
我甚至不知道键盘设备是什么。

这里针对其他笔记本电脑的所有答案都围绕使用 xset 但它对这台笔记本电脑根本不起作用！
