What are the commands to increase and decrease the brightness level in Ubuntu 17.10? It seems like
xbacklight does not work with Wayland.
I can still write the value I want on /sys/class/backlight/intel_backlight/brightness
sudo tee /sys/class/backlight/intel_backlight/brightness <<<500
But I'm trying to find the actual commands and create two keyboard shortcuts with it to increase or decrease my brightness level.
