In this case, I mean supported as in: Users in at least KDE can open their respective menu and choose Leave -> Hibernate Users can run `hibernate` ..and it just works. I'd imagine this is also the case in GNOME, though I don't use it actively to verify on real hardware, and that it works in qemu doesn't mean it works on metal. If it doesn't work on real hardware, that's a GNOME-specific issue. -- John M.
