[arch-general] Systemd screen brightness

[Michael Nawrocki]

Hey everyone,

I'm trying to get my laptop backlight keys (fn+f6/f7) to adjust the
brightness of my toshiba laptop backlight. Previously, I had entered the
following in my /etc/acpi/handler.sh to handle the acpi events generated
when those keys were pressed:

    video/brightnessdown)
      echo $(($(cat /sys/class/backlight/acpi_video0/brightness) -1)) > /sys/class/backlight/acpi_video0/brightness
      ;;

    video/brightnessup)
      echo $(($(cat /sys/class/backlight/acpi_video0/brightness) +1)) > /sys/class/backlight/acpi_video0/brightness
      ;;

However, as I am working on migrating to systemd, acpid no longer runs
and hence does not handle these events. How can I write a similar
handler into systemd?

Thanks,

Mike
