Today we go public with the Ubuntu graphics stack for the post X world. Since the beginning Ubuntu has relied on the X server to support the user experience and while it has worked generally well; it’s time for something new. My team is working on a big new component for this - Mir. Mir is a graphics technology that allows us to implement user experience we want for Ubuntu across all devices we support.
In many ways, Mir will be completely transparent to the user. Applications that use toolkits (e.g. Qt, GTK+) will not need to be recompiled. Unity will still look like Unity. We will support legacy X applications for the foreseeable future.
This is a big task. A lot of work has already been done and there’s a lot more to go. We’re aiming to do incremental improvements, and you can find more about this on the Wiki page and in the blueprints. You can help. From today our project is public, it’s GPL licensed and you’re welcome to use the source and propose changes.
It’s exciting times, and I hope you enjoy the results of this work!
