The actions for the event of a sleep button could be modified as in
EVENT_BUTTON_SLEEP="notify suspend_to_disk"
. In this case, the
user is informed about the suspend by a pop-up window in X or a message on the
console. Subsequently, the event
EVENT_GLOBAL_SUSPEND2DISK
is generated,
resulting in the execution of the mentioned actions and a secure system suspend
mode. The internal action
notify
can be customized using the variable
NOTIFY_METHOD
in
/etc/sysconfig/powersave/common
.
/etc/sysconfig/powersave/cpufreq
Contains variables for optimizing the dynamic CPU frequency settings and whether
the user space or the kernel implementation should be used.
/etc/sysconfig/powersave/battery
Contains battery limits and other battery-specific settings.
/etc/sysconfig/powersave/sleep
In this file, activate the sleep modes and determine which critical modules should
be unloaded and which services should be stopped prior to a suspend or standby
event. When the system is resumed, these modules are reloaded and the services
are restarted. You can even delay a triggered sleep mode, for example, to save files.
The default settings mainly concern USB and PCMCIA modules. A failure of
suspend or standby is usually caused by certain modules. See
Section 28.5.4,
“Troubleshooting” (page 522) for more information about identifying the error.
/etc/sysconfig/powersave/thermal
Activates cooling and thermal control. Details about this subject are available in
the file
/usr/share/doc/packages/powersave/README.thermal
.
/etc/sysconfig/powersave/disk
This configuration file controls the actions and settings made regarding the hard
disk.
/etc/sysconfig/powersave/scheme_*
These are the various schemes that adapt the power consumption to certain deploy-
ment scenarios. A number of schemes are preconfigured and can be used as they
are. Custom schemes can be saved here.
