I can get my screen to blank using either of 2 methods. Either via settings/Screensaver (on the app menu, not system settings menu), which brings XScreenSaver, or I could configure this in powerdevil. Which is preferred? I think the screensaver route is better, because some players know how to deactivate the screensaver, but don't seem to know about powerdevil. But, that's yet-another-daemon. I think this can be confusing.
