Running Raspbian on a Pi3B. Connected by HDMI and USB, the touch feature works, but only as if with a left click on a mouse. No mulitouch or long hold = right click. Device is specified as a 5-point touch screen. When plugged into my Windows machine it works straight-away with multitouch.

Any suggestions as to how I can enable multi touch on the pi?
