The X Input 2.1 Multi-Touch Implementation Is Here

Canonical's Chase Douglas has corralled Daniel Stone's X Input 2.1 Multi-Touch patches and have readied them for integration into the X.Org Server and related software components.

The patches for the xorg-server, protocol, and input drivers are now available on the mailing list. There's also an X Input 2.1 Multi-Touch PPA for Ubuntu users seeing as all of the interest Canonical has had in multi-touch (with their own multi-touch framework and proposing an X Gesture Extension) and their plans to ship greater multi-touch support in Ubuntu 11.04 regardless of what's pushed upstream in time.

Unfortunately, it doesn't look like X Input 2.1 with this multi-touch support will be pushed in time for X.Org Server 1.10 due out early next year. There's a few weeks left before the xorg-server 1.10 merge window closes, but it doesn't look like Chase at least is actively trying to get this work completed in time. "The xserver source code is essentially 1.9 plus a backport of the X input ABI 12 work. I believe it should be trivial to rebase the xserver patches on top of master, and I will likely do so after the merge window closes for 1.10 on Dec 1st."

So for X.Org Server 1.11 it looks like we have to look forward to greater multi-touch support with the bringing of the X Input 2.1 extension.
