click the button that would be 'start' then 'preferences' then 'compizconfig settings manager'
in the 'desktop' section uncheck the box by 'Expo' that disables the thing that happens when your mouse hits the top left corner of the screen
and under 'window management' uncheck the box by 'scale' which is the top-right of screen action.
i still haven't figured out how/where to enable 'touchpad tapping' or that scroll/pan that happens when you click the mouse wheel.
my laptop's touchpad's scroll zone is working though, without doing anything.
