multinput (Multiple mouse/keyboard input with xinput)

	------------------------------

	I have got a dual head main desktop. I always thought it would be
	nice to be able to use several keyboards and mice working
	independently. Today I learnt how to easily configure multiple input
	with xinput only to discover that my settings will always disappear
	after every reboot or logout.

	Well, the logical next step was to write an script to automatically
	activate multiple input but since I also want to be able to
	deactivate it at will I wrote two parts "start" and "stop". So the
	usage goes:

	$ multinput start

	or

	$ multinput stop

	or

	$ multinput restart

	The script can either be run automatically at startup (anacron comes
	to mind) or manually.

	Note: Be warned that this script is for personal use only. Feel free
	to adapt it to your own needs. I hope you like it and that it is
	useful for you too.

	Here it is:

	#!/bin/sh

	set -e

	# Script for personal use, to set multiple mouse/keyboard input
	# It uses xinput, so read its man page for more info. In order to
	# list your devices type "xinput list"

	MOUSE2="PIXART USB OPTICAL MOUSE"
	KEYBOARD2="AT Translated Set 2 keyboard"

	usage ()
	{
	echo "Type 'multinput start' to use multiple mice/keyboards."
	echo "Type 'multinput stop' to stop using multiple mice/keyboards."
	}

	start ()
	{
	xinput create-master multinput
	xinput reattach "$MOUSE2" "multinput pointer"
	xinput reattach "$KEYBOARD2" "multinput keyboard"
	}

	# Leave devices floating

	stop ()
	{
	xinput remove-master "multinput pointer"
	}

	if [ "$1" = "start" ]
	then
	start
	exit
	elif [ "$1" = "stop" ]
	then
	stop
	exit
	elif [ "$1" = "restart" ]
	then
	stop
	start
	exit
	else
	usage
	fi
