When I put the KDE Plasma to sleep it turns off the monitor and I hear the fans and the HDs shutting down just to back up to speed and the monitor turn on again on the blackened lock screen. So it is turning things off but immediately turn on again. I'm using X11 with Nvidia card and the proprietary driver.
