Comment 9 for bug 968218

Can you please give the libxi in this PPA a try on the oneiric machine?

It is a backport of http://cgit.freedesktop.org/xorg/lib/libXi/commit/?h=libXi-1.4-branch&id=22e9ace88d57803ecda95db7c9355a614db1902a which was shown to fix the same issue in other places, with minor changes to apply with our XI2.1 stuff in oneiric's libxi.
