For my use case multi-focus is exactly what I need, that's why I suggested using multiple wl_seats on Wayland, which is what I'm doing at the moment. On X11 this is not possible without using full blown multi-seat if I'm not mistaken. From the perspective of the user it should feel like using two separate devices. > Both touchscreens cannot be in the same wl_seat in the same > compositor > instance if they are to operate independently e.g. by two different > people. > > Well done homework, by the way. :-) Thanks! _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
