I tried to activate suspend then hibernate feature on my ubuntu 22.04. I followed the instruction of this answer, but unfortunately when I run sudo systemctl suspend-then-hibernate return error:

Failed to suspend system, hibernate later via logind: Sleep verb "suspend-then-hibernate" not supported

I activated suspend-then-hibernate in the sleep.conf. Here it contains:

[Sleep]
AllowSuspend=yes
AllowHibernation=yes
AllowSuspendThenHibernate=yes
AllowHybridSleep=yes
#SuspendMode=
#SuspendState=mem standby freeze
#HibernateMode=platform shutdown
#HibernateState=disk
#HybridSleepMode=suspend platform shutdown
#HybridSleepState=disk
HibernateDelaySec=50min

My laptop is a Lenovo Thinkbook 14 G2. Is my laptop not supporting suspend-then-hibernate feature? Or I missing something?

update:

Prior to that I had 10GB swap, but now I upgraded to 16 swap and still not working.

(base) mycom@mycom:~$ free -h
               total        used        free      shared  buff/cache   available
Mem:            15Gi       5,4Gi       5,4Gi       1,1Gi       4,6Gi       8,6Gi
Swap:           15Gi          0B        15Gi

When I run systemctl hibernate also returns a similar error:

Failed to hibernate system via logind: Sleep verb "hibernate" not supported

  • Do you have a swap partition? How much RAM do you have? What is the size of the swap partition? – user68186 Mar 10 '23 at 22:13
  • @user68186 I have 16GB RAM and 10GB swap partition. – Muhammad Dyas Yaskur Mar 11 '23 at 01:07
  • You need a bigger swap partition. 1.25 times the RAM. The whole comments of the RAM must fit in the swap plus whatever may be in the swap at that time. Search this site for his to increase the swap partition. The process is harder for encrypted partitions. Update the question after increasing swap if the problem continues. – user68186 Mar 11 '23 at 03:47
  • I didn't see the updated question when I wrote the above comment. The other possibility is this motherboard does not support Linux hibernate. Hibernate is not enabled by default in Ubuntu because it does not work in many computers. – user68186 Mar 11 '23 at 03:54
