If you want to shutdown your system by simply pressing the power button, do the following:
#Install the [[acpid]] package.
#If there is no ''hal'' in the DAEMONS array in [[rc.conf]], add ''acpid'' to the DAEMONS array.
#Create a file in ''/etc/acpi/events/'' named ''power'' with following content:
# /etc/acpi/events/power
# This is called when the user presses the power button
event=button/power (PWR.||PBTN)
To be able to test it, start the acpid daemon:
# /etc/rc.d/acpid start
From now on, pressing the power button (lightly, not for a few seconds) should properly shutdown the system.
Note that if you have '''hibernate''' configured and working you may want to change the last line with:
However, if you're using more sophisticated WM, you should use its own shutdown call, so it'd save its session etc.
To accomplish it in '''KDE 3''', simply change the action to:
''action=/opt/kde/bin/dcop --all-users --all-sessions ksmserver ksmserver logout 0 2 0''
For '''KDE 4''', dcop is being phased out in favour of dbus, so as well as the above you could also use:
''action=/usr/bin/qdbus org.kde.ksmserver /KSMServer logout 0 2 0''
'''''Note:''' More information on using dbus is [http://samwiseandthestereotypical.blogspot.com/2008/09/using-dbus-and-ksmserver-to-logout-and.html here].''
Likewise for '''XFCE4.4''' change the action line to:
''action=echo POWEROFF | /usr/lib/xfce4/xfsm-shutdown-helper''
'''''Note:''' For a more robust solution (If you are facing frequent WM crashes or working on a sacrificial PC for developing or testing your software...), you should take a look at "/usr/src/linux/Documentation/sysrq.txt", which is a kernel facility for yielding you (the user...) the CPU so that it could be used for any '''rescue''' work.''
