I have recently installed Ubuntu on my new Asus G56Jr laptop. I noticed that despite all the other Fn+fX keys are working, the screen brightness does not.

I have already tried editing the grub, as many here earlier advised, with no result. Also I tried using various drivers. ATM I am using the NVidia binary driver 331.38 and my grub file looks like this:

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force acpi_backlight=vendor"
GRUB_CMDLINE_LINUX=""

I know this has been already asked plenty of times, but I couldn' t find any working solution.

edit

Unlike many others I can actually set the brightess in Settings.
