[SOLVED]Issues with swap partition and hibernation.

05 December 2021, 07:12:51

After many years away from linux distros, I have artix suite 66 xfce up and running on my old dell latitude E6410. I have solved most of my issues with artix and arch wiki/forums as well as internet searches. I am still having some issues getting my swap partition to stay active and in turn causing hibernation not to work. I followed the instructions on the arch wiki to activate the swap partition as the system did not do that automatically after installation. I modified the /etc/fstab as per those instructions to enable the swap partition at boot but it is not doing that.

I have attached the terminal outputs requested for help and the /etc/fstab file.

On a side note, I have not posted on a forum in years. Is there a wiki or instructions somewhere to make my post better with in-text terminal outputs and the like?

Thank you for the hard work you all put into making this distro. What you are doing is very important to the future of the linux environment.

If another Linux was installed after your /etc/fstab has been created (or modified last time), then chances are that swap partition UUID is changed. Installers like to silently format swap partition without saying anything to the user, thus changing its UUID after formatting.

As a simple first check, I'd verify that /etc/fstab uses actual UUID for swap partition. To list all partitions with their UUIDs:

Code: [Select]

lsblk --fs

To make hibernation work, you need 3 things:
1. An entry in /etc/fstab with the swap partition.
2. An entry in /boot/grub/grub.cfg (usually taken from /etc/default/grub, array GRUB_CMD_LINE_DEFAULT) which points to your swap partition.
3. The 'resume' hook in /etc/mkinitcpio.conf, run mkinicpio -P after modifying it.

Here are mine:

Code: [Select]

#/boot/grub/grub.cfg
GRUB_CMDLINE_LINUX_DEFAULT="root=/dev/disk/by-label/ROOT resume=/dev/disk/by-label/SWAP"
#/etc/fstab
/dev/disk/by-label/SWAP		swap		swap	defaults 0 0

You can replace the 'disk/by-label/SWAP' part with e.g. sda3, whatever your swap partition is.

1. The UUID's match in /etc/fstab.
2. I modified /etc/default/grub and regenerated /boot/grub/grub.cfg
This is where it fails. If I reboot, the swap partition is not active, I can use swapon from a terminal, but it will not do it at boot.

This is where it fails. If I reboot, the swap partition is not active, I can use swapon from a terminal, but it will not do it at boot.

Try this,

Code: [Select]

$sudo 66-env -t boot -e vi boot@system

change,

Code: [Select]

SWAP=!no

Code: [Select]

SWAP=!yes

Save the change and exit. Then do,

Code: [Select]

$sudo 66-enable -t boot -F boot@system

or reboot.

Many thanks for all your help. I think a combo of the grub fix and the suite-66 boot fix did the trick. I now have swap and hibernation working as intended.
