Hello,

I'm running Mint 17.1 Rebecca (based on Ubuntu 14.04), and experiencing the same brightness problem.

I think I have a workaround; not very "elegant" but does the job.

Install the brightness applet (I'm using the one available in MATE). When you use it to change the brightness, surprise, it doesn't work.

However, if I close the laptop's lid, let it sleep, then open the lid again, the brightness seems to get adjusted to the last brightness settings I set before closing the lid.

I know, not very elegant, but seems to do the job.

BTW, my laptop is a Lenovo W520. Using "discrete graphics" option in BIOS. Output of "lspci | grep -i vga":

01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [Quadro 1000M] (rev a1)

HIH,

Sergio
