As the title says. When the computer goes into hibernation, I have to power it down to use it again.
From looking into it, I suspect the problem is that the system tries to suspend to the SWAP partition, which my basic installation of Artix (OpenRC installed with the graphical installer, I don't remember changing anything during the setup process) has neither a SWAP partition nor file:
$ free -h
total used free shared buff/cache available
Mem: 31Gi 3,7Gi 26Gi 100Mi 2,0Gi 27Gi
Swap: 0B 0B 0B
$ lsblk

I am seeing the same error as here (https://bbs.archlinux.org/viewtopic.php?id=291563) on system startup
ERROR: resume: no device specified for hibernation
From what I understand I would normally specify my SWAP partition to use and regenerate GRUB config, but I do not have a partition to give GRUB.
I have followed a bunch of other Artix forum posts (in particular, this one (https://forum.artixlinux.org/index.php/topic,1195.0.html)), my
/etc/elogind/sleep.conf is as follows:
[Sleep]
AllowSuspend=yes
AllowHibernation=yes
AllowSuspendThenHibernate=yes
AllowHybridSleep=yes
AllowPowerOffInterrupts=no
AllowSuspendInterrupts=no
SuspendState=mem standby freeze
SuspendMode=suspend
HibernateState=disk
HibernateMode=platform shutdown
HybridSleepState=disk
HybridSleepMode=suspend platform shutdown
HibernateDelaySec=10800
I also added
resume to my
/etc/mkinitcpio.conf:
HOOKS="base udev autodetect modconf block keyboard keymap consolefont filesystems resume fsck"
and ran
mkinitspio -p linux, but the problem persists.
How do I set up hibernation without SWAP? In one forum post, someone suggested disabling hibernation entirely, which would be fine by me–I'm just worried about the computer power consumption and noise and "shallow" sleep will help with that–but I don't know how, and the forum post in question didn't specify that.
You need something like this in
/boot/grub/grub.cfg:
resume=UUID=ff972c96-f909-3322-aba4-80c1f99dd605 resume_offset=371488656"
UUID is the partition's where the swapfile resides (
blkid) and offset the value given by
# filefrag -v /path/to/swapfile | awk '$1=="0:" {print substr($4, 1, length($4)-2)}'You can of course use LABEL instead of UUID or just the partition's device name (e.g.
/dev/sda2). See https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate for more details. You may also need to shift the
resume hook to the left, after
udev.
After reading the Arch wiki page more carefully, hibernation does
require having a swap partition or file, and I don't want to bother setting up swap so I'll try disabling hibernation with elogind
[Sleep]
AllowSuspend=yes
AllowHibernation=no
AllowSuspendThenHibernate=no
AllowHybridSleep=yes
...
I also shifted the hook as suggested. I'll see if that works a bit later
Or with the nohibernate kernel parameter if one doesn't use elogind.
There is this legacy piece of software called TuxOnIce, not maintained anymore so probably works just in old kernels, it hibernated like windows to an arbitrary file, with no swap. This kind of becomes useful now as there are systems out there just with zram/zswap and no actual disk swap.
Sorry for the delay between posts, this is annoying but not system-breaking.
The above changes I made to the elogind configs have not helped, the system still locks up and seems to still go into hibernation even though I think I disabled it, since I'm still seeing the "no hibernation device" error. I also tried setting HibernateState to mem instead of disk, thinking that would make it suspend to RAM but still, no luck. Why is the system even hibernating in the first place? You guys have any other suggestions?
