Hello Linux Geeksters. As you may know, Cinnamon is a GTK+3 desktop environment developed by the Linux Mint team as an alternative to the good old GNOME 2.

The latest version available is Cinnamon 2.4.5, which has been recently released, coming with a big list of changes. Among others, some memory usage improvements have been added, the Super+E key combination now opens the user’s home dir, support for single-button touchpads has been implemented, actions for 2-finger and 3-finger clicks are configurable, the screensaver can now be personalized, the users being able to change the font and text color, the desktop font is now configurable, the theme and background settings has been redesigned, support for background slideshows has been implemented and the colors of the folder icons can now be changed.
In this article I will show you how to properly install Cinnamon 2.4.5 on Ubuntu 14.04 Trusty Tahr system.
While the official Cinnamon PPA has been discontinued, Cinnamon 2.4.5 is available via some third party PPAs, so installing it is easy. All you have to do is add the ppa to your system, update the local repository index and install the cinnamon package.
But first you need to purge the nemo with Unity packages available via the WebUpd8 PPA and the Cinnamon Nightly PPA (if installed). The below three commands will not harm your computer anyway, so you can run them, just to be sure:
$ sudo apt-get install ppa-purge
$ sudo ppa-purge ppa:webupd8team/nemo
$ ppa:gwendal-lebihan-dev/cinnamon-nightly
And now, we need to add the Cinnamon PPA, update the local repository index and install the cinnamon package. Like this:
$ sudo add-apt-repository ppa:tsvetko.tsvetkov/cinnamon
$ sudo apt-get update
$ sudo apt-get install cinnamon
Optional, to revert the changes, do:
$ sudo ppa-purge ppa:tsvetko.tsvetkov/cinnamon
