I also went into this issue "system is asking for authentication to suspend" running Xubuntu 17.04 Zesty Zapus.
But luckily I figured out, this behaviour came when I set "lock session automatically when screensaver is activated" in the security tab of XFCE power management. Setting it back to "never", suspending the system is working without authentication again. Hope that hint helps finding some better solution. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1605189 Title: Authentication is required for suspending the system Status in systemd package in Ubuntu: Confirmed Bug description: Automatic suspend from the xfce power manager does not work, as a window opens and asks for my password. Well, if it wants to suspend the system after a given timeout, I cannot enter my password as I'm not in front of my system then. Once I'm able to enter my password it is too late to run the suspend action.
