Ubuntu 11.10 desktop 3D Cube effects enable

按照这篇指南搞了之后，快捷工具栏不见了，幸好下面还有高人：

Heres How I got the cube to work in very few steps:
Get compiz app. run it.
UNCHECK UNITY plugin.
goto general options->desktop size, set horizontal to 4, vertical to 1, and # of desktops to 4.
check the cube, tell it to stop using wall or w/e.
check rotate cube.
recheck the unity plugin, and tell it to ignore the conflict.
Done.
