In powerdevilprofilegenerator.cpp we can find the following

        QSet< Solid::PowerManagement::SleepState > methods =
Solid::PowerManagement::supportedSleepStates();

       //...

        KConfigGroup handleButtonEvents(&acProfile, "HandleButtonEvents");
        handleButtonEvents.writeEntry< uint >("powerButtonAction", LogoutDialogMode);
        if (methods.contains(Solid::PowerManagement::SuspendState)) {
            handleButtonEvents.writeEntry< uint >("lidAction", ToRamMode);
        } else {
            handleButtonEvents.writeEntry< uint >("lidAction", TurnOffScreenMode);
        }

Now on Kubuntu 12.10 the contains() query is always false thus the
lidaction is turn off screen. However it should not be false because...

me at novalis:~$ qdbus org.freedesktop.PowerManagement /org/freedesktop/PowerManagement org.freedesktop.PowerManagement.CanSuspend
true

solid::powermanagement uses the same dbus interface to get its
information, so one gets to wonder why it works for me and not for
solid.... turns out that this interface is provided by the very same
daemon that creates the config (why that does not sound dangerous at all
:S). My assumption at present is that either the initialization order is
wrong (i.e. the config is created before the interface) or the upower
code is bogus (race condition in init or something).


Reproducible: Always
