It looks like xrandr is passing the request with the wrong output up to
the server. Then the server probably clears the primary status before it
fails to setup the new primary output. So there's no primary output
anymore. Patch welcome :)

Most hardware do not support more than 2 (not-cloned) outputs at the
same time anyway :)
