Not sure if this is worth anything but I have been using lubuntu 16.04 for a while now and had occasional problems with suspend. I thought I'd give some of the other desktops a try and ended up going through a world of pain (and many lost hours...). For starters pm-hibernate showed the behaviour reported above and pm-suspend was far more fickle. Whatever was being called when I just closed the laptop was causing freezing upon attempting to get the desktop back - I tried experimenting with changing what was in /etc/systemd/logind.conf but it didn't seem to matter (not that I'm sure what that file does...) - hard reset was always necessary.
In any case, removing ubuntu-desktop, kubuntu-desktop and all associated packages, then reinstalling sddm and chosing lightdm as my default DM (not sure that last part was necessary) has everything back working how it was before my misadventures with more "advanced" desktops... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1562093 Title: [Dell Inc.
