Thanks to jkyahoo101 @ ubuntuforums.org

First of all I installed emerald and its themes but I cannot get themes and can't see the differents so I asked in the ubuntuforums.org and found out that we have to use emerald for windows decorations instead of compiz-fusion

Solutions:

  1. install compiz setting manager
    • sudo apt-get install compizconfig-settings-manager
  2. Goto System -> Preferences -> Advanced Desktop Effects Settings
  3. in filter type decorations you'll find the window decoration, click on it
  4. in command you'll see, /usr/bin/compiz-decorator. Changed it to emerald --replace
  5. Enjoy!!!

Note: I found out the problem about mouse pointer when I changed the pointer it's not changed all but it's changed while the pointer is in the panel area!!!!! who can explain this problem please leave the comments!
