使用 MacBook 6,1 时 Ubuntu 中的背光修复问题？

我最近在 MacBook 上安装了 Ubuntu 以进行双启动。但是，亮度功能不起作用！只有在我更改显示驱动程序后才会发生这种情况。我使用的是 Ubuntu 13.04

奇怪的是，我使用的 Nvidia 驱动程序在上面的输出中没有显示为正在使用。它是NVIDIA binary Xorg driver, kernel module and VDAPU library from nvidia-310

如何修复计算机的亮度？

答案1

安装这个 deb：

https://github.com/guillaumezin/nvidiabl/raw/master/install/deb/nvidiabl-dkms_0.81_all.deb

加载模块：

sudo modprobe nvidiabl

将其粘贴到您的 /etc/X11/xorg.conf 中：

Section "Device"
   Identifier     "Device0"
   Driver         "nvidia"
   VendorName     "NVIDIA Corporation"
   Option         "RegistryDwords" "EnableBrightnessControl=1"
   Option         "NoLogo" "True"
   Option         "AllowGLXWithComposite" "true"
   Option         "DPMS" "1"
   Option         "OnDemandVBlankInterrupts" "1"
   Option         "RegistryDwords" "EnableBrightnessControl=1; PowerMizerEnable=0x1;    PerfLevelSrc=0x2233;PowerMizerDefault=0x3"
EndSection

现在亮度控制应该可以工作了。
