Simply editing [the answer](https://askubuntu.com/a/76951/225694) to improve accuracy would seem to be the easiest course of action. As [unity](https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=unity) and [compiz](https://packages.ubuntu.com/search?suite=all&section=all&arch=any&keywords=compiz&searchon=names) and [ccsm](https://packages.ubuntu.com/search?suite=all&section=all&arch=any&keywords=compizconfig-settings-manager&searchon=names) are still available for all currently supported versions of Ubuntu. This I have done.
