Display brightness settings

Hi list,
I am trying to understand the logic behind the changes in power management
settings from Gnome 2 -> 3. In particular, the removal of the separate
display brightness settings for battery and AC mode. This seems to have
been not merely a GUI simplification, as the settings don't exist in dconf
either. My question is why this was done, since the display backlight is a
major consumer of power on laptops. Every other OS/desktop environment
allows this kind of dimming behaviour to be configured with varying levels
of granularity. At first I thought the 'dim to save power' option might
cause the display to be dimmed automatically when I unplug AC power, but
that does not seem to be the case.
In my view at the absolute bare minimum users should be able to configure
brightness settings for AC and battery modes, and possibly also also
dimming levels for each of these. Dimming to 20% brightness might be fine
on one machine, while on another it might make the display totally
unreadable.
If it is a matter of developer resources to get this functionality into
Gnome, I would gladly offer up my time to get the task done.
Sincerely,
Chris Dekter
