Description Federico 2022-01-22 10:35:15 UTC

Currently, when user is idle, logind SetIdleHint method is not called.  
This is needed to communicate to any external utility that the desktop is in idle mode (eg: screen is dimmed).  

In this particular case, the feature is useful for my own [Clight](https://github.com/FedeDP/Clight) project (an utility to manage automatic brightness either using Ambient Light Sensors or webcams)  to properly run using KDE dimmer (without using the dimmer provided by Clight itself), because it listens on IdleHint changes to understand when the automatic backlight calibration should be paused.

Is this feasible?
Thanks!
Federico

Should be fairly straightforward to add this in https://invent.kde.org/plasma/powerdevil/-/blob/master/daemon/powerdevilpolicyagent.cpp
