Looking at the most recent log in comment #6 again, that was back when you had fwupd and boltd running. I wonder if you could provide a system log from a night where those were disabled?
journalctl -b0 > journal.txt I'm still particularly skeptical of fwupd because it appears that caused a redetection of your Dell monitor at Jun 12 06:17:31, which probably also turned the monitor on. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1882462 Title: Displays wake up pre-maturely (likely driven by notification) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1882462/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
