Hello.

I'm almost there with my new laptop: one of the last missing thing is 
touchpad properly working.
ATM it doesn't work in terminal (but I can live with that), and it 
partially works in X: movement is ok, two finger vertical scrolling 
works, tapping works, but no right button or double clicking.

Actually I'm finding contrasting info on how to try and configure this; 
also it's hard to tell if info is fresh or stale.
I tried:
_ hw.psm.synaptics_support="1" + moused_enable="YES" + xorg config, as 
suggested on https://wiki.freebsd.org/SynapticsTouchpad;
_ no such changes, but using xf86-input-synaptics;
_ none of the two, just xf86-input-evdev + xf86-input-libinput.

All three seems to give same results.
So before I start digging in more deeply: which is the way to go?
