can full disk encryption interfere with waking up from hibernation?

I'm use Arch + Gnome 43 with full disk encryption and my laptop can't wakeup after hibernation. This problem with any kernel, I check linux, linux-lts, linux-zen and linux-hardened. I found information that hibernation is disabled in the hardened kernel, but the question remains open for other kernels.

Did you check here?: dm-crypt/Swap encryption/2    With suspend-to-disk support

there is a certainty that the problem is in encryption? ok, I'm reinstall Arch and check it. also, a ~year ago everything worked without swapping

If the swap is encrypted, then the kernel cannot resume from swap unless it can unlock the volume first.

See dm-crypt with suspend-to-disk.

Why would you need to reinstall Arch? What do you mean 'without swapping'?

No.
Hibernation works perfectly well with encryption, you just have to configure your system properly.

swap file/partition required for hibernation with encrypted disk?

Yes, you absolutely need a swap space on a physical device to do hibernation, doesn't matter whether your disk is encrypted or not.

Re: can full disk encryption interfere with waking up from hibernation?

Hey folks, yes a swap partition is required for suspend to disk(hibernate aka suspend to disk)! (your boot loader needs this information too!) where should the state be persisted? If you are interested in suspend(supend to RAM) see this article https://wiki.archlinux.org/title/Power_ … _hibernate

Note, if you have sensitive data on your system ensure SWAP is encrypted. And in general what are you trying to archive, suspend to RAM or Disk?
