/etc/X11/xorg.conf

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

加一行：

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
   Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

别加重复了，在 xorg.conf.d 文件夹下：

grep -r “nvidia” ./

看看有没有其它的 nvidia 字符串。
