    Description

      I noticed that touch was not working. First I found this problem https://codereview.qt-project.org/#change,77229 which prevented the touch device being registered. Second is that if I put a printf in QWaylandInputDevice::Touch::touch_frame I can see that it's never called. So I googled and found this

      It's like never getting an EV_SYN from the evdev interface (but I can see SYN_REPORT with evtest). I wonder if we could get by without the touch_frame callback? Otherwise it sounds like Qt and weston will not get along unless weston is fixed to send it?
