Comment 17 for bug 1381625

see my comments on https://code.launchpad.net/~kaihengfeng/unity-settings-daemon/add-brightness-limit-mechanism/+merge/277416 , high-level userspace isn't the place for changing this.

Can you please elaborate on what the actual bug is here? I. e. what's wrong with turning off the backlight on the lowest level, that seems rather desirable and straightforward to me?
