Replacing Unity on Ubuntu Quantal Quetzal with Cinnamon Desktop and Cairo Dock

I am not a fan of Unity which is the default desktop installed with Ubuntu Quantal Quetzal.

I rather like the Cairo Dock to get a Mac-like menu, application, notification, icon list thingy at the bottom of the desktop and have used Cairo Dock way back to Lucid Lynx.

I also run Cinnamon Desktop as the default desktop and run Cairo Dock at start up. I auto-hide the Cinnamon panel at the top of the screen. The notification area for icons is much better with Gnome so I need the panel to be able to see some of the IBM specific notification icons. Auto-hide at the top so you do not see the panel and it takes up zero screen space, but is still available when needed. Cairo Dock started crashing returning from sleep in one of the Oneiric Ocelot updates so it is especially good to have a backup start menu when needed.

To install Cairo Dock, I followed the steps:

% sudo add-apt-repository ppa:cairo-dock-team/ppa
% sudo apt-get update
% sudo apt-get install cairo-dock cairo-dock-plug-ins

To install Cinnamon Desktop, I followed the steps:

% sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
% sudo apt-get update
% sudo apt-get install cinnamon

To run Cinnamon, you select the desktop using the icon above the password on the Ubuntu login screen.
