Description:
daemon to suspend a system in case of inactivity
A daemon to suspend a system in case of inactivity with the aim to reduce the power consumption. Inactivity is determined by a set of configurable checks. Autosuspend periodically executes these checks, and if none of theme indicated activity, the system is suspended. . Autosuspend does not depend on X11 and desktop environments and is therefore specifically intended for (home) servers. Most available checks address these usage scenarios. Yet, also the X11 idle time can be used as a check to support graphical use cases.
