This is the fix. It's still an issue in 16.10 Yakkety with the latest drivers and everything else. I did a fresh install.

FIX BRIGHTNESS CONTROL ISSUE WITH INTEL CARD IN UBUNTU 14.04 AND LINUX MINT 17:

Open a terminal and create the following configuration file, if it does not exist:

sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf
Now we need to edit this file. You can use any editor be it a terminal one or graphical.

sudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf
Add the following lines to this file:

Section "Device"
        Identifier "card0"
        Driver "intel"
        Option "Backlight" "intel_backlight"
        BusID "PCI:0:2:0"
EndSection
Save it. Log out and log in back. The brightness control should be working through function keys now:
