(I see from your settings your screen turns off > after 60 seconds when locked). When I did this my monitor just hang (no any reaction on power button) to unhung it I needed to plug off power cord and plug it again. In result I saw lock screen and could login normally. I didn't mention this earlier, by my monitor is connected via USB Type C hub by HDMI connector. My monitor is NEC EA275WMi (the buttons it has are touch sensitive, not physical so this maybe was the cause I could not turn it off). And I remind. The issue happens in normal session. After waiting time my screen getting black (and turns off). I was moving my mouse instantly to back to session. In result by fraction of a second I can see background of lock screen, after that the screen turns black with visible mouse cursor, which I can move. BTW. I tried back to normal session by switching to text terminal, killing sddm and go to TTY with sddm again. I got login screen, but in result of login my monitor just hung (details I described this on begin this post). This behavior I observe since couple weeks (lock screen I tested today). Let me know if you need any additional information about my hardware or configuration of KDE/Plasma. BTW. I reported similar issue: 475632 where monitor turns off in moment of login to plasma session. -- You are receiving this mail because: You are watching all bug changes.
