-When watching someone working with an iBook I noticed that the brightness automatically faded to the lowest level after a few seconds of inactivity. I think that this is a simple way to save power. I wrote a c-daemon which uses the XScreenSaver extension to check whether the user is active. If he is not, it lowers the brightness to a specific level. When he is active again, the brightness is reset to the previous level.
+When watching someone working with an iBook you may notice that the brightness automatically fades to the lowest level after a few seconds of inactivity. This is a simple yet effective way to save power.
 {{NOTE|This Feature is implemented in the "gnome-power-manager" (at least from gnome 2.14) and can be used without this script (Prerequisites are needed anyway). Enable it under Gnome's Power management settings ([[:Category:Debian|Debian]] Etch: Gnome-Menu/Desktop/Preferences/Power Management) -> General-Tab -> "Dim the laptop panel when idle". "when idle" in this case means, when the gnome-screensaver sets the session idle. Change time at Gnome's Screensaver settings ([[:Category:Debian|Debian]] Etch: Gnome-Menu/Desktop/Preferences/Screensaver). If you want to see the actual content of the screen when dimmed, you should disable "Activate screensaver when session is idle".}}
