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.
