View source for ACPI action script optimized for R51

This is a complete [[acpid]] and [[tpb]] script optimized for a Thinkpad [[Category:R51|R51]]. It is intended to be used by advanced users (as, for example, it gives control over the CPU frequency to the user instead of running a frequency daemon)

It's features include
* screen blanking / screensaver
* hibernate / suspend
* (un)load wlan driver
* enable/disable lcd/vga
* change CPU frequency
* ... See the beginning lines of the script for more detailled information.

 ## Configuration #####################################################
 # X11 access for osd_cat and xset dpms
 USER="foo"					# Main user of this PC
 export XAUTHORITY="/home/foo/.Xauthority"	# X authority file
 export DISPLAY="auto"				# Default display
 
 # Screen saver
 # You might want to insert xlock here.
 LOCKAPP="/usr/local/bin/alock -auth pam -bg blank -cursor none"
 
 # WLAN device driver
 WLAN_MODULE="ipw2200"
 WLAN_PARAMS=""
 # or: WLAN_PARAMS="rtap_iface=1"
 
 # Which application to run on "zoom" key
 # In my case, start a network autoconfiguration tool AS ROOT!!
 # You might want to use "su ${USER} -c <foo>" here
 zoom_do() {
 	xterm -title "Network autoconfiguration" -e /usr/local/lib/net/network
 }
 
 ## Help ##############################################################
 # 
 # Installation:
 #  Copy to /etc/acpi/default.sh for acpid and symlink to tpb.sh to use it
 #  as a callback script for tpb.
 #  Run
 #     echo enable,0xffff >/proc/acpi/ibm/hotkey
 #     /usr/bin/tpb -d --callback="/etc/acpi/tpb/tpb.sh" -m on -x off
 #  on startup.
 #
 # This script enables the following features:
 #  * F1: Change to performance or powersave govenor (CPU)
 #  * F2: dpms force off (Blank screen)
 #  * F3: Lock screen
 #  * F4: Suspend to ram
 #  * F5: Bluetooth on/off
 #  * F7: VGA out on/off
 #  * F8: LCD on/off
 #  * F12: Suspend to disk
 #  * Change to performance on AC-plug-in
 #  * Change to powersave on AC-unplug
 #  * Hibernate on battery power < 5%
 #  * Spindown HDD on lid close
 #  * Poweroff after pressing the power button TWO times
 #  * Load and unload wlan driver on "Access IBM" button
 #
 # You'll need the following tools to use all features:
 #
 #  * /usr/sbin/hibernate	Hibernate script
 #  * /usr/sbin/radeontool	Radeon graphics settings
 #  * /usr/bin/osd_cat		cat'like X11 tool
 #  * /usr/bin/xset		Xset (Not installed by default with modular Xorg)
