Looks like Upower has been devuan-ified as the package in the repo has devuan in the package name, was there some systemd that needed to go bye-bye?

Maybe need updated upower in jessie for power manager to work right.

Problem is when using Mate desktop and Mate-power-manager, it is supposed to use icons for the tray/notification area provided by the power manager package and located in /usr/share/mate-power-manager/icons/hicolor/*, these icons change according to power status, i.e. battery full, battery low, etc.

I have never gotten this to work in Devuan mate, it acts as though it can't find the icons and is defaulting to using a GTK dialog warning icon (yellow triangle with exclamation point), it does this no matter what icon set you choose.

Have tried copying the proper icons into various icon directories in /usr/share/icons, but no luck with that either. Nor does updating icon cache seem to help.

The polling system is not working properly to begin with, that may be why it's showing the warning-dialog icon,  it's not checking the battery or the charging system periodically like it's supposed to,  and so not changing the icon and the tooltip info on current charge status.

Anyone else having this issue? Any ideas? Am I missing a package somewhere?
