Description Swâmi Petaramesh 2022-12-13 06:40:03 UTC 
Suspend then hibernate support does not work at all

STEPS TO REPRODUCE
In KDE settings, power management, check the “On suspend, hibernate after a certain time” box. 

OBSERVED RESULT
Aftet suspend, the system will never hibernate.

EXPECTED RESULT
Should hibernate “after a certain time” (which is unfortunaltely not precised, nor settable)

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Manjaro Linux kernel 6.0.11
KDE Plasma Version:  5.26.4
KDE Frameworks Version:  5.100.0
Qt Version: 5.15.7

ADDITIONAL INFORMATION
On the same machine using Cinnamon instead of KDE, suspend then hibenate works perfectly - per setttings in /etc/systemd/sleep.conf as Cinnamon itself doesn't know about it.

Also, in KDE the “On suspend, hibernate after a certain time” box can always be checked, but is saved only if an auto-suspend timeout is set, which is annoying because on may want the system not to go to suspend automatically, but go to hibernate after some time whenever it has been manually suspended.

We fixed that part by revamping the Energy Saving settings to be less cluttered and (hopefully) make more sense. I haven't looked into the meat of the main reported issue though (sorry).

Sorry we were not able to look into this further. Can you still reproduce the issue in Plasma 6.3.5 or later? Thanks a lot!
