I'd like to be able to hibernate another one of my Debian/KDE machines because it's practical and I'd like to save some energy.
I can't hibernate another one which has a swapfile and Secure Boot currently disabled.

The machine runs Debian10/KDE, has Secure Boot enabled and currently doesn't have a swapfile but a swap-partition (which is larger than the RAM). The hard disk is fully encrypted. I already tried the following:

• In the DE I went to Leave but unlike on my other machine there is no entry for "Hibernate". When I search for "Hibernate" the button appears but I can't right click it for more info and nothing happens when I click it.


• Installing uswsusp and then running sudo s2disk. This returns:

s2disk: Could not open the snapshot device. Reason: Operation not permitted

• Installing hibernate and running sudo hibernate. This returns:

hibernate:Warning: Tuxonice binary signature file not found.  

UdevQt: unhandlet device action "unbind"  

UdevQt: unhandled device action "unbind"  

UdevQt: unhandlet device action "bind"  

UdevQt: unhandled device action "bind"  

• Installing pm-utils and the executing sudo pm-hibernate. This returns nothing and nothing happens.


• Running sudo systemctl hibernate.

Failed to hibernate system via logind: Sleep verb "hibernate" not supported

Searching syslog for "error" or "hibern" doesn't show anything.

Is it because of security issues? I intend to change the swap-partition to a swapfile later. Hibernating with Secure Boot should be fine when the disk is fully encrypted.

  For some reason I only got this to work with openSUSE installer and its handling/configuration of GRUB2. I assume that you are using LVM on LUKS with /, /home and swap all inside the LVM container?

  Please post your kernel commandline (cat /proc/cmdline, it needs resume) and lsblk output.

  sudo lvdisplay shows that all 3 partitions are inside the volume group. cmdline has: BOOT_IMAGE=/vmlinuz-4.19.0.5-amd64 root=/dev/mapper/Debian-root ro quiet apparmor=1 security=apparmor. lsblk also shows all 3 partitions being part of the same crypt container. What do you mean with it needing resume? Do I need to edit uswsusp.conf and grub as described here?: wiki.debian.org/Hibernation/Hibernate_Without_Swap_Partition

  Let's stay with a swap partition for the moment and get it to work because I believe doing that in a file is more complicated. I see your problem and will start with an answer when I can access the laptop where it works.
