It can sometimes be convenient to have a laptop first "Suspend" to RAM, for quick wake-up -- but then automatically save RAM to disk, and power off. This combination of suspend-then-hibernate has been dubbed "Suspend Sedation" by Microsoft. For information of how to enable such behaviour with systemd, see: SystemdSuspendSedation. The acpi-support stuff is Ubuntu-specific, though.

Edit the SystemD hibernate service using sudo systemctl edit systemd-hibernate. It's tested against a stock Ubuntu This worked for me, thanks for the writeup!

Currently there are three methods of suspending available: suspend to RAM usually called just suspend , suspend to disk usually known as hibernate , and hybrid suspend sometimes aptly called suspend to both :. Using low level interfaces directly is significantly faster than using any high level interface, since running all the pre- and post-suspend hooks takes time, but hooks can properly set hardware clock, restore wireless etc. The most straightforward approach is to directly inform the in-kernel software suspend code swsusp to enter a suspended state; the exact method and state depends on the level of hardware support.
