Arch Linux shutsdown instead of hibernating

Hello world,

Some times the power gets cut off from my laptop to not kill the battery. I have Arch zen and XFCE, I tried suspend but that is S3, so all the data is lost when the battery dies. I tried the hibernate option in the power management but that just shuts down the laptop.

Also would be cool if it could automatically go to hibernate after x time in suspended mode.

Alvast bedankt

Need more information. What is your laptop model and CPU. Some systrms have known ACPI issues and thus cannot do standby/hybernate unkess you blacklist stuff ir build dkms modules.

Have you read through the hibernate docs?

https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Hibernation

That’s the first step for debugging these things.

I had actually forgotten to put the resume hook in my mkinitcpio.conf file.

Now my sleep works :stuck_out_tongue:

Thanks!

Yea, sorry, I forgot ro include.

I did read that but didn’t get much of it. I have a swap space setup and I always create one double the size of the DRAM.

Good, that’s the primary requirement.

Well, I’m not really in a position to walk you through the entire thing. What didn’t you understand?

Generally, you need to do the following:

  1. ensure your swap file/partition is large enough
  2. make sure resume hook is enabled in initramfs
  3. make sure the initramfs knows where to find the swap file/partition you’re hibernating to.

The doc above verbosely discusses those three (and more) activities.

Might be worth looking into. I haven’t actually played with this tech though, so I can’t really speak to it.
