SUMMARY *** There is no response from KDE when pressing the shutdown button or the logout or hibernation button. These buttons are of course included in the KDE menu. *** OBSERVED RESULT Only Ctrl + Alt + Backspace helps. This happened after the last update to version 5.24.3. I checked it on a desktop computer and a laptop, both are just as bad. I log into X11, Wayland doesn't work for me.
