I'm running KDE on a ThinkPad T495, and I've had a longstanding problem where the machine does not suspend when the laptop lid is closed. Anecdotally, I think it does suspend sometimes, maybe after a considerable delay.
Yesterday I noticed that the option to control what happens when the lid is closed is missing from PowerDevil entirely:
Does this have anything to do with my issue, and is there a fix for it?
I also tried uncommenting and then editing the following three options in /etc/systemd/logind.conf to both 'suspend' and 'ignore', but it changed nothing, and I presume that PowerDevil is inhibiting them from being acted on anyway:
HandleLidSwitch=ignore # and suspend
HandleLidSwitchExternalPower=ignore # and suspend
HandleLidSwitchDocked=ignore # and suspend
I also checked the output of systemd-inhibit --list:
➜ sudo systemd-inhibit --list
