tbh, I can't tap without moving, my touchpad is too sensible. it
always moves by a few pixels at least.

if you're on the window bar, the event never goes to xev, it's captured by
the WM. try doing it _inside_ the xev window, that should show events.

I can't remember any changes to this extent going into the driver. maybe
it's a side-effect of other change but you'd have to look at the state
machine in the driver where exactly the problem is now.

there's only one touchpad driver.
