Description
Power-device enumeration, event reporting, and battery history can be provided to desktop components through a UPower daemon built without systemd unit support. This package is for systems that need the freedesktop power abstraction used by panels, settings apps, and power monitors.
Power daemons affect suspend, low-battery behavior, device reporting, and desktop notifications. Test laptops and UPS-backed systems carefully, because wrong policy or patches can cause missed warnings, premature shutdowns, or ignored critical battery states.
