Comment 17 for bug 281284

Jaunty again: installed kpowersave, it responds to fn-f4 and suspends. On resume it reports a suspend "error -1" that wasn't present with Intrepid. But at least it sees the key press event and suspends.

lsof shows me that kded4 and krunner have loaded /usr/lib/kde4/ /usr/lib/kde4/

So powerdevil is there, it just doesn't seem to react to fn-f4.
