olpc-powerd 23-2 (amd64 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.
