KDE Power Saving Setting - Changing Hibernation Delay Value Does Not Work

Hello,
I am having trouble changing the default hibernation delay (from the start of sleep) from 180 min to anything else. It seems like systemctl sleep-then-hibernate uses the value of HibernateDelaySec= in the /etc/systemd/sleep.conf but KDE Energy Saving does not respect that value when the option “While asleep, hibernate after a period of activity” is selected.
I have tested the automatic suspend → hibernation behavior with both suspend to memory (sleep) and and suspend to both (hybrid sleep).

I cannot help you with this but I must say that I admire everyone who has enough patience and time to test if things like this work or not :wink:
