I tried that and it didn't work on my work ThinkPad (also those steps are dangerous it could brick your system if you so much as make a single mistake).

But that doesn't answer my question of why something as basic as Hibernate (copy RAM contents to HDD on power-OFF, then reverse on power-ON) isn't something that works out of the box on Linux distros, and instead requires 2h of tutorial reading and dangerous low-lvel tinkering for it to (maybe) work or brick your system if you mess it up.

It worked out of the box on my Arch install. I'm running a LUKS volume which holds an LVM with the ext4 fs for the system and the swap.

I'm also running TPM + PIN / FIDO2 unlocking.

Didn't need to fiddle with anything. The most part of this install was going through the manual process of creating filesystems and whatnot.

Bonus points compared to Windows for actually staying asleep instead of randomly waking up while in my bag.

Ubuntu isn't Arch I think. Average Joe switching away form Windows isn't gonna start learning Arch.

That doesn't happen under hibernate. You used sleep thinking it was hibernate, that's why you had that issue.

I mean, while asleep, the PC blinks its annoying light every second. While hibernating, it doesn't. I'm pretty sure there were no blinky lights, they would have prevented me from falling asleep. It's why I went out of my way to enable hibernating.

Also, see the other posts around the thread. There are absolutely ways to wake up a PC from hibernation. Even from full shutdown.

The Linux kernel disable hibernation when secure boot is enabled for security reasons (it enables the lockdown mode). I don't think it's especially an Ubuntu/distro problem. When secure boot is disabled, I think hibernation is supposed to work fine.

It works fine with secure boot enabled on my arch install.

But I do use a unified image which the UEFI boots directly (EFISTUB, no grub or anything). I don't know if that makes a difference.

Do you have any links on this kind of image? Or did you build it yourself?
