=== What is acpid? ===
+
{{languages|Help:Editing}}
"ACPID is a completely flexible, totally extensible daemon for delivering ACPI events. It listens on a file (''<code>/proc/acpi/event</code>'') and when an event occurs, executes programs to handle the event. The programs it executes are configured through a set of configuration files, which can be dropped into place by packages or by the admin." ([http://acpid.sourceforge.net/ acpid Sourceforge])

== Preparing to install ==
+
=== Kernel configuration ===
+
Before we are ready to emerge acpid, it is a good idea to modify a few things in the kernel. If you have not modified your kernel before, you may want to check out the following page on configuring a kernel manually (page to be added..).
+
 
+
{{kernelop
+
|Power management and ACPI options --->|<pre>
+
[*] ACPI (Advanced Configuration and Power Interface) Support
+
</pre>}}
+
 
+
==== Optional: Other ACPI features ====
+
Below are the locations and short descriptions of the function of different ACPI options in the kernel. In the majority of cases, you do not have to alter any of these to have a functional ACPI system.
+
 
+
* '''AC Adapter'''
+
{{kernelop
+
|Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > AC Adapter
+
</pre>}}
+
{{Note}} If you have a system that can switch between being plugged into AC and using a battery (i.e. a laptop), you should compile this option into your kernel.
+
 
+
*  '''Battery'''
+
{{kernelop
+
|Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > Battery
+
</pre>}}
+
{{Note}} As its name would suggest, this option adds or removes support for the battery. More specifically, through /proc/acpi/battery. If you have a laptop or other mobile system, you should probably compile this into your kernel.
+
 
+
* '''Button'''
+
{{kernelop
+
|Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > Button
+
</pre>}}
+
{{Note}} This driver handles power, sleep, and other buttons. This driver is recommended because it is necessary for software controlled power-off.
+
 
+
* '''Video'''
+
{{kernelop
+
|Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > Video
+
</pre>}}
+
{{Note}} Implements ACPI extensions for integrated graphics devices. Also adds support for setting up a video output.
+
 
+
* '''Fan'''
+
{{kernelop
+
|Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > Fan
+
</pre>}}
+
{{Note}} Allows user-controlled applications to control fan speeds and access status of fans.
+
 
+
* '''Dock'''
+
{{kernelop
+
|Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      [ ] Dock
+
</pre>}}
+
{{Note}} Builds support in the kernel for docking stations like the Dell Module Bay and the IBM Ultrabay.
+
 
+
* '''Processor'''
+
{{kernelop
+
|'''Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > Processor
+
</pre>}}
+
{{Note}} Helps save power while processor is idling and is required by several cpufreq drivers.
+
 
+
* '''Processor Aggregator'''
+
{{kernelop
+
|'''Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > Processor Aggregator
+
</pre>}}
+
{{Note}} Allows the host system to practice logical processor idling (a way to reduce power consumption)
+
 
+
* '''Thermal Zone'''
+
{{kernelop
+
|'''Power management and ACPI options --->|<pre>
+
ACPI (Advanced Configuration and Power Interface) Support --->
+
      < > Thermal Zone
+
</pre>}}
+
{{Note}} Enables support for ACPI thermal zones. It is encouraged to enable this option, as your system may be damaged without it.
+
 
+
== Installing acpid ==
+
=== Emerging ===
+
After configuring the kernel power management options, we are ready to install {{Package|sys-power/acpid}}. To install acpid, run the following command:
+
<console>
+
###i## emerge -av acpid
+
</console>
+
 
+
=== Adding to rc ===
+
After you have finished emerging acpid, you may want to add it to the list of rc services to be started with your system at boot.
+
<console>
+
###i## rc-update add acpid default
+
</console>
+
Then, run the following to start acpid:
+
<console>
+
###i## rc
+
</console>
+
