There are many guides on how to configure multimedia hotkeys using program such as xev or keyTouch. However, this guide explains how to use the simple utility of acpi_listen and generate your own script for hotkeys.
Who Should be Using This Guide
This guide assumes that you know your keyboard signals through acpi. If you do not know whether or not this is the case, I suggest looking: -Multimedia Keys in Linux -Hotkeys -Extra Keyboard Keys - keyTouch
Installing Necessary Tools
You should already have these tools installed, but just to make sure you will need
sudo pacman -S acpi acpid acpitool
Refer to this guide on what modules you should load (i.e. through /etc/rc.conf or modprobe)
Under root, or with sufficient access to the input devices, run:
If pressing a special key, such as previous or next, receives a response that looks similar to:
hkey VALZ 00000000 00000b31
then all is well and we can continue.
A Sample Script
As keyTouch and other keyboard programs did not work for me, or did not work effectively, I needed to create my own script that runs in the background and reacts directly from the output of acpi_listen. Here is the script, feel free to use it / modify it to suit your needs and post suggestions on how it can be improved. Currently, it is setup for a Toshiba Satellite A50 laptop to control exaile, but can be modified very easily for Amarok, Xine or other non-music related functions (internet, email).
export STOP_MYHOTKEY=0 i=`acpi_listen -c 1` case "$i" in "hkey VALZ 00000000 00000b31") #echo "PREVIOUS" exaile -p ;; "hkey VALZ 00000000 00000b32") #echo "NEXT" exaile -n ;; "hkey VALZ 00000000 00000b33") exaile -t ;; "hkey VALZ 00000000 00000b30") #echo "STOP" exaile -s ;; *) #echo "ELSE: $i" ;; esac e=`echo $STOP_MYHOTKEY` if [ "$e" != "1" ] then ./myHotkey.sh & fi
Note: This does not need to be run as root if you can receive an acpi_listen response from a user account (again, meaning you have access to the input devices).
