NAME

       powersaved  -  supports  APM  and  ACPI:  three  battery states, proper
       standby/suspend, cpu frequency scaling and other power management tasks

SYNOPSIS

       powersaved [ options ]

DESCRIPTION

       Daemon  that  waits  for  apm and acpi events or for socket connections
       from an authorized user.  It may  also  generate  self  defined  events
       while polling the hardware (battery, cpu, temperature).

OPTIONS

       -v     Set the debug level, allowed values: 0-31
                1  Error
                2  Warning
                4  Diag
                8  Info
                16  Debug  e.g.   Error  +  Warning: 1 + 2 -> 3 (sum up wanted
              levels like in chmod)

       -x     Set the path to executables that will be executed  depending  on
              the        events       configuration       file       (default:
              /usr/lib/powersave/scripts)

       -y     Set the path to executables that will be executed  for  internal
              events and by the event scripts (default: /usr/lib/powersave)

       -d     Daemonize process

       -f FILE
              The  file  powersave  daemon  gets  informed  about ACPI events.
              Default is /proc/acpi/event.  You may want to provide the socket
              file  of  the acpid to access ACPI events. This allows accessing
              ACPI events for multiple services/applications.

       -c DIR Sets  the  configuration  directory  (default   /etc/powersave).
              General configuration files are:
                battery
                common
                cpufreq
                disk
                events
                sleep
                thermal

       -s DIR Setcs  the  directory  for  Scheme configuration files (new ones
              could be added and switched to, default is /etc/powersave):
                scheme_acoustic
                scheme_performance   (default scheme when working on AC power)
                scheme_powersave      (default  scheme when working on battery
              power)
                scheme_presentation

       -n     Disables CPU frequency scaling.  In case this feature may  cause
              trouble.

       -r VALUE
              Overrides  the enablement of suspend to RAM. This can be used to
              determine if the machine is capable of suspending to RAM via  an
              external  program  (e.g. s2ram) in the init script. Passing 0 as
              value disables suspend to RAM, anything else enables suspend  to
              RAM.   If the config variable DISABLE_USER_SUSPEND2RAM is set to
              "yes", this parameter is silently ignored.

       -h     Print syntax

NOTICE

       Because some features are still experimental they are  not  enabled  by
       default (e.g. standby/suspend, ACPI battery notification). You also may
       want to tune the daemon for your needs.  On SUSE systems, you  can  use
       the YaST power management module. On other systems, you can have a look
       in the config files for extended configuration (see below).

       User management is now  solved  through  DBus.   A  configuration  file
       should    be    placed   into   the   DBus   config   directory   (e.g.
       /etc/dbus-1/system.d) called powersaved.conf.  Use this file to  manage
       which users are allowed to contact the powersave service.

       There may be weird bugs which result from ACPI BIOS errors of machines.
       Please check the /proc/acpi directory and dmesg  output  for  any  acpi
       errors.   Contact  your  hardware  vendor  and  install the newest BIOS
       update.

BUGS

       Standby and Suspend to RAM using ACPI is  still  experimental  and  may
       fail  on some machines. See /var/log/susp*.log and /var/log/standby.log
       (and the fail.

       Inspiration  and  code  parts  partly  come  from  the  acpid, apmd and
       cpuspeed (former cpufreqd implemented by Carl Thompson) packages.  Many
       thanks to all developers who helped to create this software.
