Well, this pm stuff is a little nebulous to say the least. There's upower, acpid with a companion package acpi-support and, in the case of mate, mate-power-manager. I'm pretty sure all the desktop managers install the screensaver.
So I guess the mate-power-manager package would be relevant only if you had the mate desktop installed. I'm not sure about other desktops.
What I failed to inquire about in my last post is if this is a laptop or desktop
If it's a laptop does this happen on battery, ac power or both
I had a problem where the laptop mouse would shut off on battery because the pm was killing the usb port after 5 seconds of inactivity. I solved that by installing yet another pm package laptop-mode-tools
What I was attempting to do is a process of elimination with these power probes and screensaver to try an pin-down the problem.
