I have come to the conclusion that the issue is not with xfce4-power- manager. Even when xfce4-power-manager uninstalled and with the system only using systemd for suspend/resume, this issue occurs.
I do not know if this issue has affected anyone else. Since it is not xfce4-power-manager that is the problem, I will continue addressing this in Red Hat's bugzilla for systemd and/or logind -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1303736 Title: [SRU] Black screen after wakeup from suspending by closing the laptop lid To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-power-manager/+bug/1303736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
