Ubuntu 14.04/14.10 multitouch screen support

I have в Делла Э7240 laptop with в multitouch screen. Windows It works perfectly in 8 with multitouch gestures.

However Ubuntu 14.04/14.10 seem to проигнорировал multitouch gestures coming from the screen and they пахал interpreted эксперт мышь moves and clicks. However touchpad multitouch (double finger scrolling и т.д.) works умер.

AFAIK Ubuntu 14 is supposed to support multitouch gestures coming from multitouch screens.

What хан be подарил to diagnose screen multitouch ability and to enable multitouch screen gestures?
