Can't seem to get hibernation to work properly

I’m no expert on this, but the link
https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate#Hibernation_into_swap_file
shows there are more steps to be made.

Please note that I’m not using a swapfile, and never tried a swapfile. I have used swap partition, but currently no more as I have lots of RAM.
If swap partition is OK for you, then that might be easier to make work.

Thanks for the link. I wish I could use a swap partition. However cause I am using MBR, I can’t create more than 4 partitions. I have already maxed out on that.

Try this for the correct grub entry.

1. Get required information:

sudo findmnt -no UUID -T /swapfile
will give you the uuid of your swapdevice.

sudo filefrag -v /swapfile | awk '{ if($1=="0:"){print $4} }'
will give you the resume offset (ignore the two dots).

2. Add the resume information to /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="[...] resume=UUID=<the-UUID-from-above> resume_offset=<your-ID-offset>"

3. Update Grub

sudo grub-mkconfig -o /boot/grub/grub.cfg

Note that with 8GB of RAM your swapfile should be at least this size to guarantee hibernation in all cases.
Also, if your swapfile resides on a btrfs filesystem the above method of getting the resume offset will not work.

Thanks mate. It didn’t work but after adding the resume inside the HOOKS as suggested by @Tasia91 it works
