I tried the fix detailed in the first answer for this question: Brightness not working after installing NVIDIA driver

The second answer caused a failed boot and I had to fix it via Recovery.

The first answer (the one used now) has no effect. It doesn't cause Xorg to fail to start, but it does nothing.

How do I fix my brightness keys? I'm using a MacBookPro7,1 (13-inch Mid-2010) with the NVIDIA drivers installed.

I managed to solve it using the following url:

Briefly, what you have to do is to compile the nvidiadl driver and tell grub that the brightness will be handled using acpi by passing the acpi_backlight=vendor argumentto the kernel.
