As you might know I was using a patched Linux Kernel 3.2 so that my integrated Intel card was used as default. So, here’s the strange thing, although I’m not setting up BCM5974 through xorg.conf (because there’s no xorg.conf file) it seems that booting into the system by Linux Kernel 3.2 or Linux Kernel 3.10 has different behaviour.
When using Linux Kernel 3.10 if I want to right-click I need to tap with two fingers but these two fingers need to be very close one from another. The same thing happens when you want to paste some text, that is middle click. You need to tap with three fingers and these three fingers need to be very close.
