I am using an ASUS ROG laptop with NVIDIA Graphics. I installed the nvidia x server driver using the driver manager in ubuntu 18.04. My volume keys work but my brightness keys do not.
I tried updating my grub and conf file as detailed in this answer but to no avail.
What can I do to make my brightness keys work or any alternatives that I can employ, such as map the command like
sudo echo 100 > /sys/class/backlight/intel_backlight/brightness to a shortcut
