Controller (Dualshock 4 gamepad) input does not prevent screen energy saving. As a result the display turns off while one is playing a game with a controller. Reproducible: Always Steps to Reproduce: 1. Configure a timeout for turning off the screen in the System Settings -> Power Management. 2. Start a game with a controller support. I use The Talos Principle. 3. Play the game with the gamepad for a while. Actual Results: The screen turns off mid-game after the timeout. Expected Results: Controller input should count as input and prevent the screen from turning off. Kubuntu 16.04 x86_64, Nvidia drivers 367.27.
I'll add that in my case Dualshock 4 is connected via Bluetooth.
joystick/gamepad input bypasses the normal way of how input is handled. Thus the relevant framework (KIdleTime) just doesn't see the input. *** This bug has been marked as a duplicate of bug 328987 ***
