Enable Hibernation (Suspend to Disk)

State of Hibernation on Pop!_OS

Hibernation is not currently enabled on Pop!_OS by default. There are several limitations that keep this from being a default:

  • Pop!_OS' Default Partition Layout
  • Use of a non-persistent encryption key for SWAP.
  • Additional drive I/O used on Solid State Drives (SSDs)
  • Depending on alloted RAM in a system, and size of NVMe/SSD drive(s), hibernation could add notable delay on resuming a hibernation session.

However, these limitations aside, hibernation is an often requested feature for Pop!_OS. The purpose of this article is to provide steps for enabling hibernation for any users that would like it.

Enable Hibernation on an Encrypted Drive

  1. Boot into Pop!_OS Recovery

    Turn your computer off, then turn it back on and hold down the SPACE bar immediately. In the menu that appears, select PopOS Recovery, and let it boot.

    Once it boots, close out of the installation window or choose Try Demo Mode (be sure not to choose any install or repair options, as this could result in data loss. It will also mount the drive and make the next steps harder).

  2. Open Gparted by clicking Activities/Applications and searching for "Gparted" or by pressing SUPER+T to open a Terminal, and running:

  3. Disable and remove the SWAP partition. You can either right-click on the SWAP partition, and select swapoff or issue that same command in the Terminal:

    sudo swapoff

    Then click on the swap partition, click the red X to mark it for deletion, and then press the green checkmark to approve the changes.

  4. Extend the luks partition to the end of the drive.

    Click on the encrypted luks partition and select the "Resize/Move" button. Use the GUI drag tools, or number fields, to make sure the OS partition extends to the end of the drive (after EFI and recovery).


    Open the encrypted partition using these Terminal commands:

    SATA DrivesNVMe Drives
    sudo cryptsetup luksOpen /dev/sda3 cryptdatasudo cryptsetup luksOpen /dev/nvme0n1p3 cryptdata

    NOTE: In the screenshot example, the partition is called /dev/vda3. Adjust the drive name to your case (sda# or nvme#n#p#).

    sudo lvscan
    sudo vgchange -ay
  5. Reduce the size of the root volume by the size of main memory. If you have 16GB of memory, reduce the data-root volume by 16GB. If you have 32GB, reduce by 32GB, etc. Use these Terminal commands:

    free -h
    sudo lvreduce -r -L-16G /dev/mapper/data-root
  6. Create a swap volume (instead of a drive partition):

    sudo lvcreate -L 16G --alloc contiguous --name swap data
    sudo mkswap /dev/data/swap
  7. Mount the root filesystem and edit crypttab and fstab to update for the new swap location:

    Mount the data-root volume:

    sudo mount /dev/mapper/data-root /mnt

    Edit crypttab to remove the original swap partition entry.

    sudo nano /mnt/etc/crypttab


    Open fstab to copy the UUID of the swap volume.

    sudo nano /mnt/etc/fstab


  8. Add a resume target for the kernel:

    Using the UUID retrieved from fstab run this command:

    sudo kernelstub -a "resume=UUID=xxxxxxxx-xxxx-xxxx-xxxxxxxx"

    NOTE: Replace everything after UUID= with the ID of your new swap volume.


    The system is now ready to suspend to, and resume from disk.

    You can test if hibernation works by booting back into your install and running:

    sudo systemctl hibernate

    CAUTION: Hibernation, if used often, will add additional write traffic (equal to the total amount of RAM) onto SSDs, shortening the lifespan of the drives.

Desktop Integration

GNOME Extension

  1. Add Extension:

    To add Hibernate and Hybrid Sleep to the power menu, we'll need to add this GNOME-Shell extension: Hibernate Status Button

  2. Add .pkla file:

    NOTE: Pop!OS and Ubuntu require a file at /etc/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

    To create this file, run:

    sudo nano /etc/polkit-1/localauthority/10-vendor.d/com.ubuntu.pkla

    Then copy these contents into the newly created file:

    [Enable hibernate in upower]
    [Enable hibernate in logind]

Save and close the file.

Your system is now ready to hibernate!
