    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.

      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.

    Depends on your distro. You need to set up all the requirements for hibernation (like “enough swap space to store current memory contents + whatever is left in swap” and zswap doesn’t count).

    IIRC Fedora defaults to ZRAM instead of swap, so you probably need to set up a swap partition first. I don’t know if you need to disable ZRAM, but you probably need enough swap space on disk to store the contents uncompressed.

    You’ll also need to modify the kernel parameters/initramfs configuration to add the resume parameters in the right spots, or the system will hibernate but not try to resume your session on boot.

    Then there may be some selinux issues depending on if Fedora fixed them or not. I don’t think hibernation is supported by default on Fedora so you may need to tweak things like polkit files to get the permissions right.

    I believe running the command sudo systemctl hibernate should manually induce hibernation. You can use it to test if your computer even has the ability to hibernate before figuring out what permission tweaks you need for KDE. Make sure you’ve saved your work before trying that, though, as not all systems will wake from hibernation without further troubleshooting.

    You may also need to disable security settings like secure boot and/or kernel lockdown mode it hibernation might be refused.

      In the right spots? I was in the impression you only need to do that so one place, in the bootloader’s boot entry (or, yeah, if there are multiple entries then possibly each one). Which other places should I also look?

      Also, I’ve recently set up hibernateion for someone, and IIRC forgetting the resume= kernel parameter is not that critical today because it will immediately resume instead of completing shutdown.
