This is my last ditch attempt to get backlight controls working in Ubuntu 16.0.4 on my MacBook Pro 10,1 (Retina, Mid-2012) with an NVIDIA GeForce GT 650M. I'm using the NVIDIA driver version 384.111.
I have looked at a bunch of questions like this and tried every answer I could find, but nothing has worked for me. So far I have tried:
adding
setpci -v -H1 -s 00:01.00 BRIDGE_CONTROL=0
to
/etc/rc.local
including
Option "RegistryDwords" "EnableBrightnessControl=1"
in the
Device
Section of/etc/X11/xorg.conf
changing
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
in
/etc/default/grub
and then runningsudo update-grub
using
xbacklight
, which just has no effectthis thing that I didn't really understand: https://bugzilla.kernel.org/show_bug.cgi?id=105051#c37
One thing I have noticed is that the directory /sys/class/backlight
is empty. I'm thinking that may be part of the problem, but I don't understand what to do with that information.
Thanks in advance for any help you can offer!

For anyone who finds this, I found a solution by accident when I booted using an old kernel (4.4.0-116-generic). Suddenly the backlight worked!
