I have a simple openbox desktop and installed xfce4-power-manager. It
handles most events fine (battery, brightness) but there is no action on
lid close. The net is full of those reports, but most have to do with
systemd/logind, which we don't have on Devuan.
Any ideas what could be wrong in Devuan?

Btw: what are all these files under /etc/systemd/system directory? What
does a /etc/systemd on Devuan???
