Created May 10, 2021 13:52 — forked from klingtnet/enable-hibernate-arch-linux.md
Enable hiberate in Arch Linux usind kernel 4+, grub2 and a swapfile

This guide is based on the hibernate article from the Arch wiki.

  • edit /etc/default/grub and add resume as well as resume_offset kernel parameters
    • resume=UUID=abcd-efgh contains the UUID of the partition on which the swapfile resides. In most cases the swapfile resides in root, to identify the root parition's UUID run blkid or lsblk -O.
    • resume_offset=1234 is the offset of the swapfile from the partition start. The offset is the first entry in the physical_offset column of the output of filefrag -v /swapfile.
    • update grub: grub-mkconfig -o /boot/grub/grub.cfg
    • example: GRUB_CMDLINE_LINUX_DEFAULT="resume=UUID=75972c96-f909-4419-aba4-80c1b74bd605 resume_offset=1492992"
  • add the resume module hook to /etc/mkinitcpio.conf:
    • HOOKS="base udev resume autodetect ...
  • rebuild the initramfs mkinitcpio -p linux
