Comment 120 for bug 650539

William King:

From what I was able to accomplish, I think there's some confusion here.

The relevant package isn't xserver-xorg (which, after closer inspection is actually version 1:7.5) but xserver-xorg-core (and related packages, which come from source package xorg-server (confusing, I know)). Applying the patch (that's already been provided upstream, http://cgit.freedesktop.org/xorg/xserver/commit/?id=78f94f19aab66a1e5331df0ce29f36e310b4195d) to the xorg-server package, compiling, and installing the resultant packages from that that I needed (nowhere near all of them) fixed the problem for me.

As a convenience to anyone else having this problem, I've put my patched package in a PPA. Please feel free to use it, as I think it will resolve your problems.
