Version: (using KDE 4.2.0) OS: Linux Installed from: Unlisted Binary Package The powerdevil entry in the systemsettings currently doesn't use tabs to separate the different "pages". It is really hard to see that there are different pages, if you don't really pay attention. Another reason: All the other entries in the systemsettings are using tabs. To keep the consistency between the systemsettings entries, powerdevil should also use tabs. thank you
this has been fixed apparently in the meantime.
