This question already has an answer here:

I installed elementary os Loki on my MacBook Pro which has Nvidia graphics card.

With a fresh installation I can change the brightness with the brightness keys from keyboard. But if I install the Nvidia drivers then the brightness is not changing even if I change it from the power settings.

How to solve this?

Update

I tried the solution given in Loki - MBPr 15 - Screen Brightness doesn't work it does not works for me.

I have MacBook Pro 13 Inch 2009 model.

Note : I tried updating the graphics driver to the latest one but all I got was a blank screen after reboot.

I had the same issue. This is what I am doing as a workaround:

sudo apt install xbacklight

Once installed go to System Settings>Keyboard>Shortcuts>Custom>

and bind the follow commands to keys of your choice

To Decrease:

xbacklight -dec 10

To Increase:

xbacklight -inc 10
