Resume from Suspend when triggered by Lid

Hi,

I have a suspend/resume issue with KDE Plasma that appears on both my 
FreeBSD powered laptops. When I suspend by closing the lid and I resume 
by opening the lid the laptop will go back into suspend mode, usually 
shortly after the desktop has resumed. I usually have just enough time 
to enter my lock screen password before it goes back into suspend. I can 
resume again by pressing the power button and everything works as 
expected after that.

The suspend on both laptops is triggered by KDE. I have it configured to 
go into sleep on closing the lid within the power management settings. I 
do not have it configured using sysctl.

Note that when using Xfce and using the equivalent power management 
settings within the desktop environment it works as expected.

My questions are, do I have this configured correctly or do I have to 
use the sysctl way of triggering suspend? Also why does it behave 
differently on KDE as opposed to Xfce?

This issue has occurred over multiple versions of FreeBSD and KDE so I 
don't know what to detail about my system. One is with hybrid graphics 
and the other not. They are both Intel Thinkpads and 10 years difference 
in age. It's not a show stopper at present, just annoying.

Any ideas on how I can debug this?


Kind regards
Ben
