Keeping in mind that I'm _not_ using or even testing backlighting, the
place where I controlled whether the laptop got screen locked or
hibernated was in the KDE System Settings app where I disabled all
such stuff. Now the screen just goes black when the lid is closed,
saving some power, but nothing locks, sleeps, hibernates or any other
I did nothing in the kernel that I see.
