Thanks, that's useful to know. Unfortunately it's the opposite of what I
really want, because I want a specific application to use the remote and
be able to distinguish between it and a real keyboard. But if X can grab
the device, maybe my application cn grab it instead. Do you know how the
grab is achieved, with a flag to open() or an ioctl()/fcntl() or
something?
