X.org is an ancient beast that works, but is creaky. Intel has really been leading the charge to develop a new display server named Wayland. After much publicity from none other than Mark Shuttleworth about how Ubuntu was going to adopt Wayland, they decided to write their own display server from scratch named XMir. They want to use the same code for Ubuntu on phones, desktops, tablets. Intel doesn't much care to support anything other than Wayland because after 10+ years of X.org, they know better than anyone (most of all Canonical) what is best when it comes to display servers. They are putting all of their weight behind Wayland and don't see XMir as a viable future. As a result, they made a decision to not support it upstream. Their driver their call. Seems relatively cut and dry to me. As usual, another case where Canonical can't play with the rest of the open source community. Edit to add all below: I would also highly suggest anyone curious to read: http://www.phoronix.com/scan.php?page=article&item=x_wayland_situation&num=1 http://www.phoronix.com/scan.php?page=article&item=x_wayland... http://mjg59.dreamwidth.org/26254.html http://mjg59.dreamwidth.org/26254.html Those two articles are both critical of Mir, but are also from some very senior developers in the low level Linux/X related plumbing of Linux. I'd argue they are more qualified to speak about the failings of X than the Mir developers primarily because they've been the people fixing it's bugs the past many years.
