Tired of Ubuntu’s Unity desktop environment? Try Cinnamon, the latest desktop environment from Linux Mint. Cinnamon offers a more traditional, GNOME 2-like layout, but it’s based on the modern GNOME Shell — and you can install it on Ubuntu. However, you can just download their build and install it; if you choose this route, you can grab their Ubuntu 14.01 (Trusty Tahr) LTS version which is supported until April 2019 here, make sure to pick the one for your system type.
Open a terminal and type the following:
sudo add-apt-repository ppa:merlwiz79/cinnamon-ppa
Press Enter when it prompts you
second, download a list of available packages by running this command:
sudo apt-get update
Now you’re ready to install Cinnamon’s packages with this command:
sudo apt-get install cinnamon cinnamon-session cinnamon-settings
Type Y and press Enter when prompted.
Log out of your current session
At the log-in prompt, click on the gear above your login username and select Cinnamon. You can now log into your Cinnamon desktop.
Disabling the Global Menu
You might notice Ubuntu’s global menu bar still appears at the top of the screen. If you want to get rid of it, just run the following command, then log out and back in:
sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt
Want it back? Just replace “remove” with “install” to reinstall the packages:
sudo apt-get install appmenu-gtk3 appmenu-gtk appmenu-qt
