I had the same problem with a Satellite L755 (Intel only, no NVIDIA) and solved it by creating this file:

/usr/share/X11/xorg.conf.d/20-intel.conf

Giving it the following:

Section "Device"
        Identifier "card0"
        Driver "intel"
        Option "Backlight" "intel_backlight"
        BusID "PCI:0:2:0"
EndSection

After reboot the brightness function keys work! Other posts indicated needing to add acpi_backlight=vendor to grub but I don't seem to need to modify any grub settings. Just the above file solves the problem.
