There are still a lot of problems with these patches, but I want to move forward on this. I picked the first two patches and edited them to get the basics into shape, then added a few fixes on top. The evdev part was mostly fine, but the event delivery had a number of problems: - we can't overwrite device->x,y, that's the pointer position - we have to deliver the surfaces relative coordinates, not the global coordinates to clients - touch_up was never delivered since you clear touch_focus_resource just before testing it for NULL Moreover, we need to track each touchpoint position in the evdev part so that when we get only ABS_MT_POSITION_X (or Y), we have the other coordinate. Finally, we need to handle losing both the touch focus surface or the input device client resource without crashing. Most of these issues are obvious if you look at the event stream (use WAYLAND_DEBUG=1) and the missing transformation to surface coordinates would have been clear with a simple multi-touch-paint test client, like the one I added.
