I installed Kali Linux 2.0 yesterday on my Zenbook UX303LB and touch-click on my track pad doesn't work. I had the same problem in Ubuntu so it's not a new issue and I just used a mouse as a workaround. However, a couple minutes ago I discovered that I am able to scroll around a website when touching the track pad with two fingers!
Why can my touch pad detect two fingers scrolls but not one simple tap? Maybe I could configure the touch pad to recognize tap clicks?
