I recently installed Ubuntu on my retina Macbook Pro (following this great guide).
Everything works fine so far however the screen brightness / backlight cannot be adjusted neither by using the assigned key nor by any other means. I know, I'm not the first to address this problem, but all the suggested solutions I found so far did not work for me. I unsuccessfully tried the following:
- Including Option
RegistryDwords" "EnableBrightnessControl=1in the Devices Section of
- the application
- I also haven't found any file such as
apple_backlighton my system which probably would be a starting point.
I'm using the Nvidia-driver. (BTW: With the nouveau-driver, the keys to adjust the brightness work. However, with the nouveau driver Ubuntu does not resume from suspend mode)
Any suggestions what I can do? Thanks!
