Compiz is a popular compositing and window manager for Linux. It brings a host of improvements to the user interface.
In some tutorials showing you how to install Compiz, the command to be entered in terminal is
sudo apt-get install ccsm (for Ubuntu, in this case) but entering that command shows you an error “ccsm package could not be found”.
This happens because ccsm is not the name of the package (not any more). You can either use your distro’s graphical package manager, or use the command below (given for Ubuntu):
sudo apt-get install compizconfig-settings-manager
