backlight-tooler-service-toggle

For the tool to work, the systemd-service backlight-tooler-change-permissions has to be enabled and started. The systemd-user timer backlight-tooler.timer can be enabled to get automatic handling every 15 minutes. For changes of the default auto value, consider copying /usr/lib/systemd/user/backlight-tooler.service to ~/.config/systemd/user/ and edit the file from there.
