Ah okay, I've misread this. I thought it was needed. I wonder why
synaptics support must be disabled. I will check within the synaptics
tunable if there is still a way to disable the tap button.

I've also already seen this topic, they say that finger scroll is
enabled by default on their machines, it's weird that on mine two
finger scroll sysctl variable is set to 0.

My touchpad fully support two finger scrolling though.

If I can't get this I'll try the xf86-input-synaptics driver instead.
