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
