compiz-fusion: switch from Metacity to Emerald

You can easily change your window manager from Metacity, compiz’s default window manager, to the much more promising Emerald.

First you have to install Emerald:

sudo apt-get install emerald

Then you will have to tell compiz to load Emerald instead of Metacity. Edit your ~/.config/compiz/compiz-manager configuration file (create it if necessary):

gedit ~/.config/compiz/compiz-manager

Add the following line into the file:

USE_EMERALD="yes"

and save it. The next time your restart X you will have Emerald loaded instead of Metacity.
