I'm using Ubuntu 14.04 and want to stop programs switching (equivalent of Alt+Tab) in response to mouse gestures. Right now it happens all the time when I use the mouse, I'm not even sure what gestures cause it. I poked around settings but couldn't find anything related, and turning off two finger scrolling didn't stop it. If anyone has any ideas how I could customize that it would be very much appreciated!
(Further info: I use the trackpad on an asus x501a as my mouse. It's a button-less touch-area with right and left click designated in the bottom approximately quarter inch of the area)
