I just went through this a few months back... quite painful, but
productive. In the end, however, I had to switch back to APM due to
some BIOS/hw issues. You need to look in /etc/acpi/events/*
and /etc/acpi/actions/*.
In my (leftover) /etc/acpi/events/lid file (laptop) I have this:
event=button[ /]lid
action=/etc/acpi/actions/suspend.sh
In my /etc/acpi/actions/suspend.sh I have this:
#!/bin/sh
# pre-suspend actions here
/etc/init.d/hotplug stop
/etc/init.d/alsa suspend
/etc/init.d/hwclock.sh stop
# suspend
echo 3 > /proc/acpi/sleep
# when this returns, we are resuming
sleep 2
/etc/init.d/hwclock.sh start
/etc/init.d/alsa resume
/etc/init.d/hotplug start
You can create a similar events file that contains things like:
event=button[ /]power
and point it to a similar script that contains
echo 4 > /proc/acpi/sleep
which will put your system into hibernation (if I remember correctly)
