Povolení hibernace pro Ubuntu 22.04 se swap souborem:

Make your /swapfile have at least the size of your RAM

sudo swapoff /swapfile
sudo dd if=/dev/zero of=/swapfile bs=$(cat /proc/meminfo | grep MemTotal | grep -oh '[0-9]*') count=1024 conv=notrunc
sudo mkswap /swapfile
sudo swapon /swapfile

Note the UUID of the partition containing your /swapfile:

sudo findmnt -no SOURCE,UUID -T /swapfile

/dev/nvme0n1p5 20562a02-cfa6-42e0-bb9f-5e936ea763d0

Get the resume offset of your /swapfile:
- Run sudo filefrag -v /swapfile
- In the "physical_offset" column, copy the first row number (without dots). Value example: 34816.

Configure Grub to resume from the swapfile by editing /etc/default/grub and modify the following line:

GRUB_CMDLINE_LINUX_DEFAULT="resume=UUID=20562a02-cfa6-42e0-bb9f-5e936ea763d0 resume_offset=34816 quiet splash"

Update Grub:

sudo update-grub

Create the following /etc/initramfs-tools/conf.d/resume:

RESUME=UUID=20562a02-cfa6-42e0-bb9e-5e936ea763d0 resume_offset=34816
# Resume from /swapfile

Update initramfs:

sudo update-initramfs -u -k all

K povolení volby hibernace v menu upravte soubor:

sudo mcedit /var/lib/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

Přidat následující obsah:

[Re-enable hibernate by default in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

[Re-enable hibernate by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=yes

Now you can hibernate with:

From power off menu
From command line:

sudo systemctl hibernate

From command line:

sudo pm-hibernate

Troubleshooting

Check why systemctl hibernate doesn't work:

systemctl status systemd-hibernate.service
