i did all my settings through Desktop Effects. i did not use Compiz Config Settings. that latter program does not work in Ubuntu 12.10. my 8-sided cube was done in Ubuntu 12.10 with Kubuntu desktop added on. so it is possible. the settings can be hard to find but i know they exist--unless they are not available due to certain graphics card limitations? my two Ubuntu lappies have ATI cards built in
keep in mind Desktop Effects is not available in Unity, the DE that is installed by default in Ubuntu 12.10. you need to have KDE to gain access to those options.
