Novell LINUX ENTERPRISE DESKTOP 10 SP2 - DEPLOYMENT GUIDE 08-05-2008 Deployment Manual page 567

If, for example, the variable
EVENT_GLOBAL_SUSPEND2DISK="prepare_suspend_to_disk
do_suspend_to_disk" is set, the two scripts or actions are processed in the
specified order as soon as the user gives powersaved the command for the sleep
mode suspend to disk. The daemon runs the external script /usr/lib/
powersave/scripts/prepare_suspend_to_disk. After this script has
been processed successfully, the daemon runs the internal action
do_suspend_to_disk and sets the computer to the sleep mode after the script
has unloaded critical modules and stopped services.
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
"Troubleshooting"
/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.
