![笔记本电脑 ubuntu16.10 亮度控制不起作用](https://linux22.com/image/997514/%E7%AC%94%E8%AE%B0%E6%9C%AC%E7%94%B5%E8%84%91%20ubuntu16.10%20%E4%BA%AE%E5%BA%A6%E6%8E%A7%E5%88%B6%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8.png)
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

答案1
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"
