Manjaro Lysia 20.0.3 new swapfile

If you generate a new swapfile, it usually will get a new uuid. But /boot/grub/grub.cfg will not be updated automatically.

So next time you boot, error like this will occur:

ERROR: resume: hibernation device ‘7a5aa742-6133-41bd-8dc5-d72d4790d364’ not found

In this case you will have to wait a long time to get into GUI or not able to login at all.

What you should do is to edit /etc/default/grub, change GRUB_CMDLINE_LINUX_DEFAULT="quiet resume=UUID=<your new swap UUID>", and then run sudo update-grub to update /boot/grub/grub.cfg.

Check if resume=UUID=<new swap UUID> in /boot/grub/grub.cfg are set correctly.

You should also check swap UUID in /etc/fstab.

Use sudo blkid to find UUID of your devices.
