Daniel Stone has pushed out a set of 27 patches to the X.Org mailing list this morning. These 27 patches all pertain to X.Org input support and are slated to be pulled in for the xorg-server 1.12 release. Coming up in August will be xorg-server 1.11, but we just passed that merge window and so this input work will not land until the 1.12 development begins in late August or early September.
Most of the patches aren't terribly exciting alone, but with providing support for smooth scrolling it becomes interesting. Smooth scrolling, a feature already supported by other operating systems, attempts to remove the "jumpy" movement feel when scrolling down or up a page.
The patch queue starts here.
