powersaved - supports APM and ACPI: three battery states,
proper standby/suspend, cpu frequency scaling and other
power management tasks
[ options ]
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).
Set the debug level, allowed values: 0-31
e.g. Error + Warning: 1 + 2 -> 3 (sum up wanted levels like in chmod)
Set the path to executables that will be executed depending on the
events configuration file (default: /usr/lib/powersave/scripts)
Set the path to executables that will be executed for internal events
and by the event scripts (default: /usr/lib/powersave)
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
Sets the configuration directory (default /etc/powersave).
General configuration files are:
Sets the directory for Scheme configuration files (new ones could be
added and switched to, default is /etc/powersave):
scheme_performance (default scheme when working on AC power)
scheme_powersave (default scheme when working on battery power)
Disables CPU frequency scaling.
In case this feature may cause trouble.
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
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.
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
resume) log files to figure out which module/HW component could cause
