Hi,
PowerDevil maintainer here. Unfortunately, I haven't had much time to
look after PowerDevil, but I agree that a logarithmic scale for screen
brightness makes sense.
Perhaps PowerDevil can even abstract that way from the user, so the UI
in Battery Monitor for instance stays linear 0-100% but is then
translated internally by PowerDevil.
I might propose a change to the default
brightness control behavior. If it is not, I would ask for [sanction to
work on] configuration options that would allow users to change from
linear to nonlinear adjustment.
Patches welcome :)
> I also think that the ideal number of steps is less than 20, possibly
closer to 10, and I wonder how much of that original choice of 20 might
have been influenced by the brightness of the lowest step (5% vs 10%).
If the lowest step can be closer to 1%, that decision might deserve a
second look.
There's no real reason, just so that one brightness up step results in a
5% change just as one volume step up does. I typically use the mouse
wheel on the battery icon, though, where you can freely adjust the
brightness without any steps whatsoever. I think 5% is still a bit
coarse currently but, as you said, might become less of an issue if we
were to go logarithmic.
Cheers
