Bug Description
This machine is an HP Envy x360 touchscreen hybrid laptop. On upgrade from 15.10 to 16.04, multiple finger touches / gestures no longer perform actions in the user session as they did before. This includes the unity window controls.
I believe as well that pinch used to work when running Google Maps in Chrome -- this now also fails. I don't know if it's possible that means it's a symptom of another problem. I'm not sure what tools at https:/

Update: mtdev-test appears to show that the number of fingers touching the screen is correctly interpreted. I assume this is the case because I see a number in the output that is always one less than the number of contact points. However, I really don't have any idea how to interpret the other parts of the output (as others have noted in the past: http:// ubuntuforums. org/showthread. php?t=1766341 ). So I can't be sure that it is understanding dynamic multitouch gestures per se if they are in fact parsed at some point before Unity looks at them. In any case, there should still be Unity window control responses from simple, static multitouch taps, and those aren't working either.
