acpi_listen does not output anything to terminal when pressing key combination.

Keyboard backlight has worked on older versions (I believe 18.04 or earlier.)

I can manually toggle with:

echo 0 | sudo tee --append /sys/class/leds/asus\:\:kbd_backlight_1/brightness
echo 1 | sudo tee --append /sys/class/leds/asus\:\:kbd_backlight_1/brightness
echo 2 | sudo tee --append /sys/class/leds/asus\:\:kbd_backlight_1/brightness
echo 3 | sudo tee --append /sys/class/leds/asus\:\:kbd_backlight_1/brightness

for varying degrees of brightness.
