Perhaps the answer lies in /etc/systemd/logind.conf with its array of
Handle*= and *IgnoreInhibited= settings.

FTR, CtrlAltDel and touching the physical power button are "soft"
ways, as opposed to the Reset button (typical on 20th century PCs),
holding down the Power button, or just cutting the power. (I always
used to disconnect the Reset button from the mobo, first thing after
I acquired any PC.)
