<title>Introduction to acpid</title>

|
|
The <application>acpid</application> (Advanced Configuration and Power
|
|
Interface event daemon) is a completely flexible, totally extensible
|
|
daemon for delivering ACPI events. It listens on netlink interface 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 user.
|
|
</para>
|
|
|
|
<note>
|
|
<para>
|
|
Some other packages may handle some ACPI events as well and they
|
|
may conflict with this package. For example, &logind;
|
|
(read the documentation for <option>Handle*=</option> in
|
|
<filename>logind.conf(5)</filename> for details) and
|
|
<xref linkend='upower'/> (used by many desktop environments such as
|
|
GNOME, KDE, and XFCE for handling ACPI events). If you've installed
|
|
such a package and it's enough for your use case, this package is
|
|
probably not needed. If you really need this package, you must be
|
|
careful configuring it and the other packages handling ACPI events
|
|
to avoid conflicts. Notably, &logind; handles some ACPI events
|
|
by default, so the handling of these events by &logind; should be
|
|
disabled first if handling these events with acpid
|
|
(again, read <filename>logind.conf(5)</filename> for details).

The following brief example will suspend the system when the laptop

lid is closed<phrase revision='sysv'> (it requires

|
<xref linkend="pm-utils"/>)</phrase>. The example also disables
|
|
the default handling of the lid close event by &logind; when the

|
system is on battery and not connected to any external monitor,
|
|
in order to avoid a conflict:

Unfortunately, not every computer labels ACPI events in the same way
|
|
(for example, the lid may be recognized as <filename>LID0</filename>
|
|
instead of <filename>LID</filename>).
|
|
To determine how your buttons are recognized, use the
|
|
<command>acpi_listen</command> tool. Also, look in the <filename
|
|
class="directory">samples</filename> directory under <filename
|
|
class="directory">/usr/share/doc/acpid-&acpid-version;</filename>
|
|
for more examples.
