Version: (using KDE 4.2.4) Compiler: gcc 4.4 OS: Linux Installed from: Unlisted Binary Package when switching between to more conservative power profiles, brightness should not increase. eg, i have powersave configuration set to 50% screen brightness and i've already decreased brightness to lower than 50%, say 30% when on the performance profile. now, when powerdevil switches from performance to powersave based on battery level, brightness increases to 50%. this is undesirable behavior . brightness should not increase when switching to a more conservative profile.
I have noticed this as well when running on battery power. I had set my back light to minimum, and when the battery dropped below 25%, and 15%, the screen got brighter. Also, when the battery got to 10% and lower, the back light would just shut off every minute or so, and I had to blindly turn it back up.
I think this is a duplicate of https://bugs.kde.org/show_bug.cgi?id=194807

This bug (or wish as it is called here...though I think it's really a bug) is still present in KDE 4.4.1.
KDE 4.5.0: bug is still here...

I was about to submit this exact same bug (ain't a wish) running 4.6beta2 on ubuntu 10.10
Another weird thing is that when the screen goes off (or you close the lid and open it again) and you move your mouse to make it on again the brightness reverts back to the profile setting and not to the brightness you had set manually (I usually have the brightness at lowest)
I just encountered this bug with KDE 4.6.4.

The behavior was bugging me a bit too much a certain day and I created a patch that I posted in my duplicate bug report: https://bugs.kde.org/show_bug.cgi?id=271659#c0 Not sure if it's the desired behavior but it is at least a suggestion for the maintainer.
