olpc-powerd 23-2build1 (armhf binary) in ubuntu bionic

 The powerd daemon can function as an easily customizable replacement for ohmd
 (independent of X, dbus, and hald). This package provides the powerd
 and olpc-switchd daemons, and related utilities. The olpc-switchd daemon
 simply provides notifications about lid and switch events. The powerd daemon
 controls display dimming, automatically putting an XO to sleep after a period
 of idleness, etc.
