Thank you for your reply. I will test kernel 3.15 and revert with news (probably later on today).

In the meantime and after reading various reported bugs, I came accross this one:

It regards dell xps13, but refers to the exact same GPU (id 8086:0116).
As you will read, the same problem persists especially on kernels after the 3.8, and they way to fix the fn function of the brightness keys in newer kernels is to set from the BIOS the "Load Legacy Option Rom" to "Enabled".

Unfortunately even if I have installed the lasted version of BIOS proposed by the DELL manufacturer (i.e. version A06), there is no option for legacy option.

I am just throwing ideas. It may help you go towards the right direction for solving the bug.

I will revert with news about the 3.15 kernel.

In case you have any suggestions, please let me know.
