So that’s not related to your hibernation issue. Regarding this one, I’d like a precision that might be useful: is this about hibernation or suspend? Other than that, what DE do you use if applicable? What does handle lid close event? I had the issue that the lid close event wasn’t handled because KDE PM daemon isn’t inhibiting systemd one correctly, and once fixed it worked again. Bruno
