But something is causing the screen lock not to be displayed (as if its > window wasn't drawn?) Okay, so then we've got two different bugs on our hands. My patch from https://invent.kde.org/plasma/powerdevil/-/merge_requests/332 should solve one. We'll still have to figure out where the other one comes from.

Right, thanks for pointing that out. Those are indeed different things, although I can only see the fade-out effect used by PowerDevil and nothing else (it sets a "_KDE_KWIN_KSCREEN_SUPPORT" atom for X11, implemented in KWin's KscreenEffect). The effect itself also triggers when a display is "aboutToTurnOff", which could be worth exploring too but seems somewhat unlikely. At this point I wonder if there's maybe a second powerdevil running (for a different logged-in Plasma session?) with the old, unfixed code that still manages to activate the fade-out effect but doesn't manage to turn off the display. I wouldn't bet on it, but what other leads do we have at this point? If it's the screen locker window not being drawn, the black screen (with visible cursor) should go away once you blindly unlock the session with your password. The fade-out effect hits all windows, whereas the screen locker on X11 is only a single window that sits on top of all the rest. -- You are receiving this mail because: You are watching all bug changes.
