Version: (using KDE 4.2.2) OS: Linux Installed from: Debian testing/unstable Packages I tend to manually decrease the brightness (using my keyboard's brightness control keys). When power profile changes, like in a low battery situation, PowerDevil sets the new brightness level as config'd in the profile, *regardless* of whether the brightness was *lower* than the profile settings. So in effect, if I set brightness to minimum, on low battery event the brightness would go UP.
I have the same problem here. There should be a possibility to disable brightness adjustment from PowerDevil. Furthermore PowerDevil should check if the brightness is lower than determined for the lower energy profile.
