As Brian, instructions to revert to official Ubuntu packages are documented on https://launchpad.net/~xorg-edgers/+archive/ppa . From these instructions:
""" To revert to official packages, install the ppa-purge package and run "sudo ppa-purge xorg-edgers". Note: This currently has issues in oneiric because ppa-purge there does not work with multiarch. ppa-purge packages from this PPA do purge correctly on precise and newer.
