to powerdevilcore so it doesn't load an action if it is not supported.</pre>

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.</pre>

On my machine it always claims "The profile Battery tried to activate DPMSControl which is a non-existent action.", which is when I compile powerdevil myself that DPMS stuff is not compiled (DPMS build requirements not met here) and so the action floats around in the config but cannot be triggered anyways. (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.</pre>
