repowerd, or some other process that acquires logind suspend inhibitions, could be involved in this. It's easy to find out if this is the case by running:
$ systemd-inhibit and checking if any inhibitions with parameters What:sleep Mode:block are active. Note that repowerd acquiring such an inhibition just means that another program has requested a suspend inhibition from repowerd. In any case, as discussed in bug 1668596, repowerd will soon stop acquiring logind suspend inhibitions. ** Changed in: repowerd (Ubuntu) Status: New => Fix Committed -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-session in Ubuntu.

When clicking on the "Suspend" button in the session indicator, nothing happens. This may or may not be an indicator-session issue. I need to triage this and see where the breakage is, e.g. does it work in Unity 7 on Zesty, and are there are any DBus signatures that have changed in Zesty that would cause this To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1674389/+subscriptions -- Mailing list: https://launchpad.net/~dx-packages Post to : dx-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~dx-packages More help : https://help.launchpad.net/ListHelp
