Work-around Solution for Ubuntu 12.10
For those of you on 12.10 that are trying to use the 1.13 Xorg version, you can add the "precise" (a.k.a. 12.04) repos to your /etc/apt/sources.list file (just duplicate the "quantal" lines you have and change quantal -> precise). in order to DOWNGRADE Xorg to version 1.11 along with the dozen or so dependencies. It does work, I'm currently still running 1.11 core Xorg. I.e., I did not do a complete upgrade from 12.04 (precise) to 12.10 (quantal) because of this issue.
