Comment 280 for bug 541492

I don't have much experience in that area so I can't be sure, but I think it would need to be backported. It will probably show up in the xorg-edgers PPA soon. See https://launchpad.net/~xorg-edgers/+archive/ppa?field.series_filter=precise for detail on how to install and uninstall. Note in particular the warning to install the whole PPA and not just individual packages from it. The other option is to compile it from source on your machine - see https://help.ubuntu.com/community/CompilingSoftware
