eglfs supports display of mouse cursor only in Qt. I added this in https://codereview.qt-project.org/#change,23118. You should be able to backport it. As for mouse input, double check if the input device path (/dev/input/mouse0) is correct. Just put a debug in the input plugin. The mouse should also probably be plugged in before the program starts since the mouse input plugin doesn't support udev (the qt5 version supports it though) Girish _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
