Hi,

running 1.0.10 on Debian Sid on a Thinkpad X201s (thus hit by #7541, but that does not matter here). The machine has 16 possible brightness levels (0-15).
Xfpm is set to dim to "20%" (whatever that means exactly in levels) if the machine is idle for 120 seconds.
That if fine most of the time, but not if my current brightness is at level 0. In that case my screen will become *brighter* (set to level 2 or something) when the idle timeout kicks in. This is obviously wrong :)

There are two possible ways to "fix" that:
1. set to idle_brightness (20%) only when current is more:
   set_idle_brightness() {
      if current_brightness > idle_brightness {
         set_brightness(idle_brightness)
      }
   }
2. always set to 20% of the current:
   set_idle_brightness {
      new_brightness = current_brightness * idle_brightness_percent
      set_brightness(new_brightness)
   }

I would prefer number 2, but I bet others would differ :)

Thanks for your work
Regards
