For quite some time now, KDE has intermittently been unable to go to sleep. It will either go to a black screen with the cursor still showing, and the computer running, or it will show a half frozen sddm looking screen with the computer still running. The computer, in both cases, will be wholly unresponsive, and the only way to get out of it is to forcefully shutdown the PC by, for example, holding the power button.
i've been having a similar issue where if i shake the mouse at a certain point of it attempting to suspend then the screen will go black with the mouse present and i have to restart to bring it back
