Ubuntu unveils its next-generation shell and display server
In evaluating the options, Canonical decided that the X server needed
replacing, and that Wayland was not viable for running on handheld devices.
The new solution, Mir, is designed to run both on the system-on-chip (SoC)
hardware found in phones and on standard desktop graphics hardware. The port
of Unity from the OpenGL-based Nux toolkit is a reversal of sorts, Ries noted,
but when Ubuntu halted work on its previous Qt-based implementation of Unity
(the "fallback" mode for systems without sufficient graphics power to run
Nux-based Unity) it did so in large part because Qt's future was uncertain.
The project was in the midst of a hand-off from corporate owner Nokia to a
community-governed council, and it was not clear that the Qt-based Unity
would offer a comparable feature set to the OpenGL version. Now that Qt is
in a stable and healthy position, Ubuntu has resumed work on the Qt-based
Unity.
簡單的說 就是 Wayland 在手持式裝置上是不可行的 要滿足 C 社目前的目標
必需要自行開發一套能在各個平台上跑的 compositing window manager
至於為什麼之前有用 Qt 來寫 unity 後來放棄 然後現在又開始用 Qt
原因是之前 Qt 被 Nokia 買走 對於 Qt 的前途 走向不明 所以放棄 Qt 版的 unity
現在 Qt 是 open project 發展的很穩定 所以重新使用 Qt 來寫 unity
然後也提到另一篇 blog 條列了很多項目說明 為什麼要做 Mir

最後 文章很長 我還沒看完 上班先 :p
Canonical's Chase Douglas subsequently did join the Wayland mailing list,
and on at least one occasion he weighed in on a design issue. The topic
was touch input support in particular, in February 2012, and Douglas did not
seem pleased with Wayland's touch event handling, noting specifically that
it would not work when the user was sending touch events to more than one
application. Most mobile platforms do not support having multiple foreground
applications, but the tablet builds of Ubuntu Touch do.
Touch event handling is an interesting case to consider. The Mir wiki page
cites input event handling as one of the project's points of disagreement
with Wayland. It goes into frustratingly little detail on the subject, but
Ubuntu is clearly interested in multi-touch and gesture recognition support
due to its push on tablets and handheld devices. It debuted a multi-touch and
gesture input stack with the release of Ubuntu 10.04, which it still maintains.
Wayland, meanwhile, has stayed focused primarily on the desktop.
In August 2012, there was an effort to revive the dormant weston-tablet-shell,
although based on the commit logs it has been receiving less attention subsequently.
