is ubuntu phone (or tablet) use X for display server? if so, it should change the Ubuntu Desktop Application to Ubuntu Phone (or tablet) its much easier for developers.
if not, what Display Server is used?
I watched Jono Bacon talk answer a question about this on a ubuntuonair webcast, just a couple of weeks ago. As far as i can remember he said that it used the same server as Android. They are not going to use x (and neither would it be wayland). bit of a shock that:) To see what he had to say exactly you would have to watch the webcast. Ubuntu On Air has a channel on youtube Cheers
