pm-suspend and pm-hibernate are deprecated. Now it's done via systemd
(isn't everything?). I expect the Gnome extension just calls that but I
use KDE so I wouldn't know (the KDE hibernate/suspend does work).
See 'man systemd-suspend.service'.
One thing to check: you must have enough free space in swap or the
hibernation will fail (though suspend should still work). Use 'free' to
see how much free space there is and add some more if it's not enough.
How do you know how much is enough? It depends on your workload so you
basically guess, which is pretty much what you do with swap space
anyway.
The old "rule of thumb" for swap space was twice your RAM size (16GB
RAM = 32GB swap). Few people do that now, but disks are relatively
cheap. I still use the 2x rule but I've been a Unix geek for 40 years
and it's hard to teach this old dog new tricks:
