the server decides which client gets MT and which one gets an emulated pointer on a per-client basis. your test program that registers for XI 2.2 won't see pointer emulation, but xev still should. Last I checked, this worked here. either way, there's nothing you need to do in the kernel driver. if you speak the MT protocol B, the rest should be handled automatically.
