acpi acpid and power menagement Slackware

Unfinished but if Power management troubles You it works now!

http://www.thinkwiki.org/wiki/How_to_make_use_of_Dynamic_Frequency_Scaling# - Read This

If hardly want to Read
http://www.acpica.org/downloads/index.php
http://www.lesswatts.org/projects/acpi/faq.php - can read it but it seems old

In kernel src
make menuconfig
Power management select all acpi options even is marked as depreciated

recompile restart with new kernel

acpid must be happy and started if not look at /etc/rc.d/rc.acpid and make it runnable +x

get "speedfreq" and compile

See the source below load all acpi modules

This is what i load more of them are not need!

Here is mine bash function src :

### ACPI CPU
function acpi_cpu {

# ACPI & CPU modules
#
modules=`ls -q /lib/modules/2.6.28/kernel/drivers/acpi/; \
ls -q /lib/modules/2.6.28/kernel/drivers/cpufreq/; \
ls -q /lib/modules/2.6.28/kernel/arch/x86/kernel/cpu/cpufreq/;`;
for i in $modules; do
modprobe $(echo "$i"|cut -d"." -f 1);
done;
[ -x /usr/sbin/speedfreqd ] || { echo "/usr/sbin/speedfreqd - not found, exiting "; return; }
### [ "$?" -eq 0 ] && success $"$base startup" || failure $"$base startup"
speedfreqd -u # -u user can mod

echo "$? ACPI CPU FREQ Modules loaded. SpeedFreq Started";

} ### ACPI CPU END

P.S>
cpufreq - is not recommended yet - after start crash.

On most motherboards APM not work with Dual Core and etc processors if work he disable one of the cores!

see that file: /etc/acpi/acpi_handler.sh - it is ACPID default action you can change and add some functionalities.

And Now power button must PowerOff your computer.
