Compiz doesn't work with Cinnamon. If you must have Compiz, I'd recommend MATE instead of Cinnamon. Compiz can also be made to work on Xfce, though that requires more work on your part, or on KDE but as KDE already has its own desktop effects for wobbly windows, desktop cubes, and so on, that is a bit pointless in my opinion. If you search for "compiz" on the Community site tutorials, here http://community.linuxmint.com/tutorial/search
, you will find at least one tutorial for enabling Compiz on Linux Mint 15 MATE (but the others there may be helpful also if you run into problems).
