I’ve made it work on arch, debian and fedora, on a T420s, T480s, T14 AMD, MBPr 2012, each on luks2 + btrfs with systemd-boot, and it works flawlessly on all of them. the setup is super-involved and cumbersome though but it’s easily accomplished once you get the hang of it.
the links posted here along with the arch wiki is what I used. it helps if it’s not your primary and only device, so you have time to retry until you get it right.
Did you encrypt your swap as well? I used to use hibernation back in the day but without LUKS encryption.
Ever since I’ve started using LUKS encryption, I never bothered with hibernation again, allthough I would like to.
a combination; some have swap as a btrfs subvolume, some as a swapfile in root and those are encrypted, when the system boots it requests the encryption passphrase, regardless if it coldboots or restores. restores from swap are way faster than coldboot plus all your stuff is how you left it.
on some systems I have a separate swap partition outside of luks2/btrfs and that one’s unencrypted. when it restores from there, it doesn’t request the passphrase and the boot is even faster. that’s obviously less secure but my threat model is a lost/stolen laptop, I seriously doubt someone’s gonna forensic the shit out of my swap, it’s more likeky it’s gonna get wiped and sold.
to fully utilise this tech, it’s essential to set up suspend-then-hibernate, another awesome feature that’s way too cumbersome to set up. the laptop suspends for like 60 minutes and if it’s not woken up, it hibernates to disk.
Having that button doesn’t automatically result in that feature actually working. The development stakeholders don’t seem to be interested in it actually working other than chance and given that even Windows and macOS moved to “always connected” suspend instead of full sleep with hibernation, I don’t see a push for feature parity on the horizon (that’s why Windows laptops and more recently also MacBooks often cannot wake up because the battery is depleted). It’s really bad and IMO one of the few big problems to solve (at least on my Windows notebook because of its broken regular suspend, I can force it into hibernation).
I had somewhat decent success making a swap file (not a partition):
I’ve tried to get hibernation working on like 3 different distros. Followed tutorials exactly step by step. Never works.
Linux doesn’t do hibernation. Anybody who says otherwise is not living in the same universe as me.

how come opensuse has that button

sudo fallocate --length 16600MiB /swapfile;sudo chmod 600 /swapfile;sudo mkswap /swapfile;sudo swapon /swapfile;sudo nano /etc/fstabThen add
/swapfile swap swap defaults 0 0the fstab file now open in Nano.Last time I had openSUSE hibernation didn’t work. I am just convinced that the entire linux community is gaslighting me about hibernation lol
oh
