Debian Sid, No DE, w/ i3wm

4gb RAM & swap

I am trying to setup hibernate on Acer Aspire laptop from 2017 using the guide from Arch wiki (Debian guide is outdated, checked other forums that I know but no luck)

I tried it in my swap file /swapfile, not working, then I create swap partition, still the same thing happen.

Both swap that I used is working on suspend/sleep

This is what I did to setup hibernate:

1. Add resume=UUID=45a8aaf2-70c0-4e5d-af58-01d2ae34cf6d resume_offset=1409024 to /etc/default/grub
2. Add RESUME=UUID=45a8aaf2-70c0-4e5d-af58-01d2ae34cf6d to /etc/initramfs-tools/conf.d/resume
2. update-grub && update-initramfs -u
3. reboot then systemctl hibernate

It will turn off the screen by 10 sec and turn back on, no shutdown, just nothing happens after that.

dmesg output: https://pastebin.com/bNFsdw6D

Can you give some suggestions to make this work? Any problems with my setup?

This is a complete and total shot in the dark, but . . . .

This may be because RAM and harddrive space are measured in different ways. RAM is measured in binary, diskspace in decimal.

4GB RAM in 4096 MB. 4GB HDD ia 4000 MB.

This was not the result of some kind of plot. It's just the way stuff developed in the early days of computing.

(I tried to find a citation for this, but was buried in too many irrelevant links, but I do remember reading this some while ago.)

Maybe TLP could work for you.
