In this video, I show how to fix a hibernation issue that I've been having on my Manjaro Linux operating system running on T14 Ryzen 7 laptop.
1. Look in /etc/fstab and make sure the following line is there:
UUID=[UUID_of_the_swap_partition] none swap defaults 0 0
Copy the [UUID_of_the_swap_partition] before moving on to the next step.
2. In /etc/default/grub add: resume=UUID=[UUID_of_the_swap_partition] to GRUB_CMDLINE_LINUX
3. In /etc/mkinitcpio.conf add resume to HOOKS (after udev)
Then :x to edit out of the vim editor.
4. Reload the configurations by running:
sudo mkinitcpio -P && sudo update-grub
5. Hibernate and log back in to see if that fixed the problems.
For me, the following steps fixed the problem for me.
