Ubuntu, Kubuntu, Xubuntu "Mir, Ubuntu's in-progress replacement for the X Window System, is being used internally at Ubuntu developer Canonical and will be available to all users in the next version of the operating system. Mir was announced in March, with Canonical saying that a new display server is needed to power the Unity interface across desktops, phones, and tablets." Anyone here experience with Mir? Is it any good? any downsides?

1) Complete control over the project ( so they can ensure it works exactly like they want for Unity).

2) Compatibility with Android device drivers.

Complete control over the project was part of Canonical plan since its inception. Unfortunately, history has shown that mindset led to its downfall, ask SUN. About compatibility with Android drivers, Canonical is using Surfaceflinger which turned out to be ad-hoc hack Wayland avoids:

In addition, it turned out Mir is nothing more than a modified early Wayland, Wayland itself can use Android drivers through extensions:

I think Ubuntu rightly sees a great business opportunity in having a single operating system on phones, tablets and desktop computers. I'm not sure if the cost is worth it though. I'd prefer something like KDE where you can have the same applications but with a different gui depending on your form factor ( Desktop, notebook, tablet).

Canonical made bad business decisions in this case. Wayland already reached these goal canonical tried to reach through Jolla and Tizen. The burden will be the long term maintainance of Mir in these kind of environment especially enterprise. It seems Canonical still learned nothing from their failed webTV venture.

Interesting. I had not heard how Mer planned on using Android drivers.

But I have heard that Surfaceflinger is going to be replaced by Mir in the future for Ubuntu phone. They want the same architecture as much as possible.

I agree their plan doesn't make much sense, and stinks of NIH syndrome. From the mailing lists I've read, its pretty clear that it wasn't an engineers decision to create Mir. All the questions hit a dead end at "This is what we at Canonical have decided to do". Its clear that the engineers being grilled by Wayland/KDE, et all are a bit uncomfortable with the whole situation.

I think a big reason is that they want to control the phone/tablet platform without having OEM's just use a "MobileMint" for free. They can do that by leveraging the GPL V3 license along with the CLA on Mir.

I don't begrudge them for wanting to make money from open source. I think that's a good thing (TM). But, they're kind of screwing up the ecosystem ( by creating a different Xorg replacement) to do that. That's not cool.
