Novell LINUX ENTERPRISE SERVER 10 - INSTALLATION AND ADMINISTRATION 04-08-2006 Installation Manual page 535

The directory /usr/lib/powersave/scripts contains scripts for processing
events:
switch_vt
Useful if the screen is displaced after a suspend or standby.
wm_logout
Saves the settings and logs out from GNOME, KDE, or other window managers.
wm_shutdown
Saves the GNOME or KDE settings and shuts down the system.
set_disk_settings
Executes the disk settings made in /etc/sysconfig/powersave/disk.
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 userspace or the kernel implementation should be used.
/etc/sysconfig/powersave/battery
Contains battery limits and other battery-specific settings.
