In a terminal type “mateconf-editor”
When the editor opens:
Go to /desktop/mate/session/required_components/windowmanager and replace "marco" with "compiz".
Now click menu and look for "Startup Applications Preferences" and run it
Make an entry call "Compiz Start"....actually you can name it anything
and make the command "compiz --replace"
Bring up a terminal and type "ps -ef | grep compiz"
you should see "compiz --replace" running
