Recently I upgraded from Ubuntu 11.04 to 11.04. By default 2-finger tap was set to right click and 3-finger tap (3FT) to middle click (button 3). 2-finger tap works fine when I set tap-action to x x x x 1 3 2 or x x x x 1 2 3, meaning that, it's not the middle click event that is being grabbed but the 3FT, before it even gets translated to an event defined by tap-action. Proof that 3FT is in fact detected is that whenever I 3FT inside an unmaximized window I get this: .
I followed instructions from the Ubuntu Forums but my system got really unstable for an unknown reason: from sporadic log-offs to frozen screens to tap-click not working at login. I reinstalled 11.10 because of it and now I'm posting this.
Any one can see through this problem?
