I would like to be able to hibernate EndlessOS. I successfully used @egrath’s instructions (thanks to @egrath) to enable my swap partition permanently, but I still have no idea how to configure EndlessOS for hibernating, any suggestions?
As far as i know, it’s hard to create a hibernate / resume with a Swapfile instead of a swap partition, so it may be even harder on a OSTree based system. See https://wiki.debian.org/Hibernation/Hibernate_Without_Swap_Partition for further details on why.
Thanks Egon, I have a swap partition, not a swap file, and I followed your instructions succesfully and so I was able to activate the swap partition (semi) permantly, but I have no idea, how to enable hibernate now.
First of all, make sure that Fast Boot and Secure Boot are disabled in your BIOS - those interfere with Hibernate. Then, run the following command:
systemctl hibernate
which should put your system into hibernation mode if all prerequisites are met.
results in Failed to hibernate system via logind: Sleep verb "hibernate" not supported (with and without sudo).
PS: Interestingly, my usb-stick with Debian based siduction has no problems to hibernate on the swap partition of the usb-stick.
can you please also try:
pkexec /lib/systemd/systemd-sleep hibernate
results in
Suspending system…
