Hello everyone,

Recently, I need to cut off power supply with all my running tasks saved.

But it seems that the hibernate mode provided in Debian only allows me to 

Suspend to Ram(STR, or S3 mode in ACPI).

Is there any way to Suspend to Disk (STD, or S4 Mode in ACPI) in Debian?

Thank you for your replies in advance.

Best Regards,

Richard

    Do you have a swap partition? It has to be sufficient in size and is
    necessary for Hibernation to work.
    You need to edit "/etc/initramfs-tools/conf.d/resume"
    file to provide an UUID of a swap partition, or a path,
    in case of LVM, to a swap partition and run:
    # update-initramfs -u
    
        Example for traditional disk partitioning scheme:
    $ cat /etc/fstab | grep -iE "swap"
      UUID=e990fa6d-3f82-4d65-b6a1-542e240718fc     none    swap   
      sw      0       0
      
      $ cat /etc/initramfs-tools/conf.d/resume 
      RESUME=UUID=e990fa6d-3f82-4d65-b6a1-542e240718fc
    
        Example for LVM partitioning scheme:
    $ cat /etc/fstab | grep -iE "swap"
      /dev/vg0-nvme/lv1-swap  none    swap    sw      0       0
      
      $ cat /etc/initramfs-tools/conf.d/resume 
      RESUME=/dev/vg0-nvme/lv1-swap
