## In order to execute MMB on two finger click on boot you will have to execute 
synclient TapButton2=2

Disable trackpad while typing

#### ~/.xinitrc
syndaemon -t -k -i 1 &			# after keypress, disable scrolling/tapping for 2 seconds

Configuration Options Multitouch mousepad support. Unfortunately my previous configuration required the use of xorg.conf For new computers, you can easily determine your touchpad functionality by finding it in the list from xinput -list and then using xinput list-props "SynPS/2 Synaptics TouchPad" | grep Capabilities. You will get a list of 1s and 0s which correspond to:

lmb

mmb

rmb

2-finger

3-finger
