A Working X Input 2 Implementation

X Input 2, a major rework to the X.Org input extension, is a step closer to reality. Originally it was hoped that X Input 2 would be ready for X Server 1.6, but that didn't end up happening and also resulted in Multi-Pointer X being disabled in this latest X Server release. This morning, however, Peter Hutterer (of MPX fame) has his first working X Input 2 implementation.

This code has not yet landed in the mainline code-bases of the X Server, libXi, inputproto, or xinput, so for now he has this working implementation running in his own Git repositories. Peter though has re-based this work off the latest X.Org Git code and "it works without issues" while implementing the X Input 2.0 draft specification. While X Input 2 is working, there are currently a number of limitations and there are several features still missing.

In Peter's mailing list are all of the details along with how interested parties can help out and where X Input 2.0 is going to go. What is not clear at this point, however, is whether this revised input extension will be ready for X Server 1.7 / X.Org 7.5.
