Yes, but that is not an admission of preferring systemd. ;-)

By closing the lid, it's a laptop (asus zenbook)

I think you're on to something.  When I CTRL+ATL+L the system, and then
close the lid, the post-hibernation resume works correctly (no screen
leakage).  Unfortunately changing the systemd login settings didn't
seem to have any effect.  I'm comfortable not using systemd on servers,
is it just as straight forward without it on desktops/laptops?
