Hibernate

[Goldorak]

I installed Mint 21 on a new system. Partionned with a swap partition twice the RAM. Added another partition twice the RAM for hibernation. I tried to find information on the web on how to enable hibernation. I can click on Hibernate on the Cinnamon Menu. When i do, the system takes a few seconds to hibernate (just like on Windows). But when I boot my system, it boots normally rather than using what was put into hibernation.
Any info on how to enable this last stage?
Thanks

You can try suspend too
Command is

Code: Select all

 sudo pm-suspend

You might be able to find some information here: https://ubuntuhandbook.org/index.php/20 ... ntu-21-10/
The page is actually about Ubuntu 22.04 on which LM21 is based.

My guess is that you need to add the "resume" parameter to Grub.

Note: I have not tried it, so "you are on your own".

> My guess is that you need to add the "resume" parameter to Grub.

I already have this in /etc/default/grub :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=67e00f52-9bb1-44df-9df3-2d52151d1558"

Of course I used "sudo update-grub" after that.
The UUID was copy/pasted from (GNOME) Disks.

Content of /etc/initramfs-tools/conf.d/resume :
RESUME=UUID=67e00f52-9bb1-44df-9df3-2d52151d1558

I also just did a "sudo update-initramfs" but it doesn't resolve the issue.

Astonishing. Where from did this menu entry come?

The op uses LM 21.

That works, but it's not what I need (hibernation).

It's what I followed yet it does not work.


The only difference with these guides is that I used a separate partition, not the swap partition.
Still no luck enabling Hibernation on Mint 21
It works on Windows' Desktop ...

Hibernate doesn't work for many including me . The machine doesn't wake up . Good luck for your search.

hybrid sleep mode

Code: Select all

sudo systemctl hybrid-sleep

If hibernate does not work, than hybrid sleep cannot work.

It seems (I haven't tested yet) that Hibernate works on Manjaro. Any idea why?

It differs from hardware to hardware. You can try installing the same kernel as in Manjaro and test.

Randomly this can work. But hibernation works with the very same Mint version and the very same kernel on one machine, but not on the next. So it is a trial and error game. (I would bet, that also with Manjaro hibernation does only work on some hardware, not on all.)
