maxpus=1 still suffers the same issue. I then disabled and stopped the upower daemon but the issue remains with the only common factors being systemd-logind and lightdm.
I tried console-only tests with lightdm stopped and CANNOT reproduce the issue. I installed sddm and changed the default display manager to use it: apt install --no-install-recommends sddm Tested with logind + sddm and CANNOT reproduce the issue. Re-enabled upower via the x-p-m applet. Tested with logind + sddm + upower/x-p-m and CANNOT reproduce the issue. Tested with logind + sddm + upower/x-p-m + light-locker and CANOT reproduce the issue (note: light-locker dies at some point so no password dialog on resume). Based on all this it seems to point the finger at ---> lightdm -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759950 Title: Lid-close suspend: blank screen when switching to user session To manage notifications about this bug go to: https://bugs.launchpad.net/light-locker/+bug/1759950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
