madargon, After more thinking related to my previous post (https://is-a.cat/@madargon/111845765590354051) I decided to add some kind of dead man's switch to my main laptop (to ensure disk #encryption would fully protect it in case of emergency). I read it could be possible to configure systemd-logind to shut down my computer automatically after long inactivity. So I tried to do it and now I have laptop shutting down in random moments, mostly after I open its lid after being long closed when turned on (as I understand it makes it suspended and systemd-logind doesn't work then), use it and then leave idle for 20-30 mins. And my goal was shutting it down after full 10+ h inactivity :blobfoxfacepalm:
I am not sure WHAT I am doing wrong :blobcatfearful2:
