笔记本电脑 ubuntu16.10 亮度控制不起作用

我的亮度控制选项卡住了。我有两个亮度控制键（fn + 向上或向下箭头），但它们根本不起作用。我使用的是 MSI gl72 6qf，配有 nvidia 960M。

我编辑了 /etc/default/grub，现在看起来像这样：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

（我尝试了 acpi_osi=linux；acpi_backlight=vendor；video.use_native_backlight=1 但没有任何反应）

我仍然无法通过热键更改亮度。我尝试使用 xbacklight，他回答我：“没有输出具有背光属性”。

亮度控制器和亮度指示器也不起作用。

根据系统设置，我的屏幕“未被检测到”。

当我尝试 acpi_listen 时，我的热键被很好地识别，所以它不是来自这里。

我使用的是 nvidia 驱动程序 370.28

我终于找到了我的问题的答案：

我按照我在研究期间没有找到的此页面上的说明进行操作：

https://help.ubuntu.com/community/HybridGraphics

因此，假设上述情况，进入 ubuntu 的“附加驱动程序”部分，我切换到 367.57 驱动程序，并在 /etc/default/grub 中更改此行：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

改为：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modeset=nouveau"
