I'm running Ubuntu 18.04 on a Lenovo P50

I've tried to hibernate from the command line with sudo systemctl hibernate and what I get is

Failed to hibernate system via logind: Sleep verb not supported

And also cat /sys/power/disk

[platform] shutdown reboot suspend test_resume

Some additional information:

  • Ubuntu does not support hibernate on all hardware. – user68186 May 15 '18 at 22:13

  • One obvious problem is your swap space is not as big as your memory. Your swap has to be at least the same size, so your in-memory processes can be saved somewhere. – jpaugh Dec 22 '20 at 03:35

I was getting the same error on my X1 Carbon 7th Gen. I did the following to enable the hibernation:

  1. Turn off Secure Boot in BIOS.
  2. Turn off "Modern Standby" in BIOS.
  3. Create a swap file bigger than my RAM.
  4. Update the grub using the instructions here.
