So I recently put Endeavour on another of our machines, and since it had 32GB of memory thought “I don’t need swap”, not knowing that swap was necessary for Hibernation. So I setup a swap file [following these steps](https://forum.endeavouros.com/t/adding-swap-hibernation-after-install/10831/11). After that and a restart my DE now has a Hibernate option in the power options. However, when I use it, it doesn’t actually save my session at all, and turning on the PC after a hibernate is the same as a cold boot, my session wasn’t saved at all. Has anyone else had this issue? I even tried making my swapfile bigger than my system memory to be extra sure it has enough space to save. I’ve done everything identical to the post except in `etc/default/grub`'s GRUB\_CMDLINE\_LINUX\_DEFAULT I also have ‘quiet’ and ‘nvme\_load=yes’ as they were already there and I didn’t want to mess with the existing config more. Would either of these interfere with saving/loading the state? Here are my relevant lines of the grub config ```auto GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="EndeavourOS" GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=3 resume=UUID= nowatchdog nvme_load=YES" ``` ---

You didn’t follow the instructions properly & add the UUID of the partition that has the swap file on it. Please go back and re-read the instructions from the post. ---

Ah, thanks. Should that be set in the grub config at all? I’m reading the Arch wiki on it [here](https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Hibernation), but I’m getting permission denied trying to add the value to /sys/power/resume\_offset, even as root ---

I think it needs resume=\ resume\_offset=\ [https://wiki.archlinux.org/title/Power\_management/Suspend\_and\_hibernate#Hibernation\_into\_swap\_file](https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Hibernation_into_swap_file) ---

You may find this thread very helpful. > [@Can't seem to get hibernation to work properly](https://forum.endeavouros.com/t/cant-seem-to-get-hibernation-to-work-properly/5933/4): > > I usually follow this guide when I setup hibernation. I don’t think you also set the resume\_offset properly Also, if you don’t want to type out the whole sudo grub mkconfig -o /boot/grub/grub.cfg every time you update grub. . . .yay -S update-grub ---

I’ve added the resume\_offset and regenerated my grub config, but it still does not load my session. ```auto GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="EndeavourOS" GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=3 resume=UUID= resume_offset=34816 nowatchdog nvme_load=YES" ``` 34816 comes from the physical\_offset column from `filefrag -v /swapfile`. ---
