I got what I think is powerdevil displayed on my panel (next to clock). When I left click I get a plasma. I chose suspend to ram when lid closed, but when I close the lid it does nothing. It worked with kpowersave (I believe that's the name of the older one?). If I choose suspend to ram manually in powerdevil it works. But not if I put it in the action for lid closing in the current (performance) profile.
