I just installed Ubuntu 12.04, uninstalled Unity, and installed cinnamon. Everything appears to be working normally except for one thing. In the "desktop" configuration panel inside the cinnamon management tool, they give you the option of what icons you want displayed on the desktop like Computer, Home, Trash, and mounted volumes.
For some reason, these icons do not always appear and going back into the configuration tool to "uncheck" and "re-check" them usually does nothing. Restarting cinnamon with the alt+f2, r trick doesn't work either.
