Guarding onProfileLoad won't be enough if/when PowerDevilDPMS action is patched to use KIdleTime timeouts rather than DPMS timeouts. Plus this complicates PowerDevilAction semantics, at least in my view.

Sorry I don't have anything more constructive to offer. It would be easier if there were a Solid::Display class to query in the profilegenerator, as in my original suggestion (or maybe the extremely new libkscreen might be more appropriate). Maybe this is more long term work though.

(Imho this is a really infamous message, have seen it quite often on other machines *duck*). All the other actions seem to be installed anyways, so this missing action poses no threat. I guess a kWarning would be sufficient for this.
