No Longer able to Change Brightness on Laptop w/ Keybinds

instead of xbacklight I am using brightnessctl after reading:

You should simply not use xbacklight but any of the other alternatives that are more intelligent in what they do. xbacklight explicitly relies on a functionality of xf86-video-intel that isn’t replicated in any other driver, but there’s no technical reason for this dependency to exist. acpilight provides ab xbacklight drop in binary while being able to directly adjust the relevant backlight control file regardless of the xorg driver in use.

So I changed in the script ~/.config/i3/scripts/volume_brightness.sh
the following lines:

function get_brightness {
    brightnessctl | grep -Po '[0-9]{1,3}'| sed -n '3p' 
}

    brightness_up)
    # Increases brightness and displays the notification
    brightnessctl set "10%+"
    show_brightness_notif
    ;;

    brightness_down)
    # Decreases brightness and displays the notification
    brightnessctl set "10%-"
    show_brightness_notif
    ;;

now it works again like before.
Should work for you @zangoku as well after you installed brightnessctl.
