I confirm all problems still persist in xfce on Devuan:
- no lid-based actions in xfce (only via acpi-script hack -> but this still doesn't trigger anything power-related in the xfce gui)
- no battery actions -> this is particularly annoying as you don't get warning when you run out of battery or also don't see if you are charging or not
- strangly: volume and display buttons work
- power button works sometimes (usually not)

I tried diffrent versions of xfce4-power-manager, upower, acpid - even from ceres - all don't work.

I don't actually understand why all this doesn't work? Anybody has a better idea what is missing in xfce4-power-manager?
All this does work on voidlinux (I haven't tried artix yet).
