The schemes are stored in files in
/etc/sysconfig/powersave
. The filenames
are in the format
scheme_name-of-the-scheme
. The example refers to two
schemes:
scheme_performance
and
scheme_powersave
.
performance
,
powersave
,
presentation
, and
acoustic
are preconfigured. Existing schemes
can be edited, created, deleted, or associated with different power supply states with
the help of the YaST power management module described in
Section 28.6, “The YaST
Power Management Module” (page 524).
28.5.3 Additional ACPI Features
If you use ACPI, you can control the response of your system to ACPI buttons (power,
sleep, lid open, and lid closed). Configure execution of the actions in
/etc/
sysconfig/powersave/events
. Refer to this configuration file for an explanation
of the individual options.
EVENT_BUTTON_POWER="wm_shutdown"
When the power button is pressed, the system responds by shutting down the re-
spective window manager (KDE, GNOME, fvwm, etc.).
EVENT_BUTTON_SLEEP="suspend_to_disk"
When the sleep button is pressed, the system is set to the suspend-to-disk mode.
EVENT_BUTTON_LID_OPEN="ignore"
Nothing happens when the lid is opened.
EVENT_BUTTON_LID_CLOSED="screen_saver"
When the lid is closed, the screen saver is activated.
EVENT_OTHER="ignore"
This event happens if an unknown event is encountered by the daemon. Unknown
events include ACPI hot keys on some machines.
Further throttling of the CPU performance is possible if the CPU load does not exceed
a specified limit for a specified time. Specify the load limit in
PROCESSOR_IDLE_LIMIT
and the time-out in
CPU_IDLE_TIMEOUT
. If the CPU
load stays below the limit longer than the time-out, the event configured in
EVENT_PROCESSOR_IDLE
is activated. If the CPU is busy again,
EVENT_PROCESSOR_BUSY
is executed.
