I installed Cinnamon 1.8 on Ubuntu 13.04, and now I would like to completely remove Unity and everything related to it, but I'd like to keep the programs, LightDM and Software Center.
What packages should I remove?
I decided to get my hands dirty and hunt down all files related to Unity in Ubuntu 13.04. I will share my experience in switching to Cinnamon and completely remove Unity.
I am not responsible for any damage to your system nor any loss of data. A Backup is recommended.
First you will need to add the Cinnamon PPA and install it.
After Cinnamon is installed, logoff or reboot the system and login in Cinnamon. You can customize it now, or later, it's up to you.
Now you will need to make Nemo the default file manager.
Then run the command below, if Nemo opens this means that everything is configured correctly.
Now, let's get rid of Unity.
I searched carefully at all the files related to Unity, with the help of Synaptic, and gather them all into a single command line. The next command will completely remove Unity and everything related with it, but will keep LightDM, Software Center and all the programs that comes with Ubuntu.
Please note that there are a few libraries that will remain in the system, they are necessary, removing them will break your programs and possibly the system. These libraries should remain:
gir1.2-unity-5.0 libunity-common libunity-protocol-private0 libunity9 unity-asset-pool unity-greeter
There is a Thunderbird extension called “Messaging Menu and Unity Launcher integration” that needs to be removed from its folder.
Cinnamon uses Muffin as window manager, so you can safely remove Compiz.
If you installed Nemo you can remove Nautilus as well.
Optionally, you can remove Zeitgeist, which is considered intrusive by many users, this will also free some memory and reduce hard disk access.
You can also remove configurations files related to Unity, Compiz, Nautilus and Zeitgeist, on your home directory. They are in the following paths:
Another good tip is install Bleachbit, to remove temporary files from your system.
That's it, now reboot the system to clear the memory and make sure everything is fine. If all went well, you now have a clean and elegant system running!
With Cinnamon my system became much more fluid, especially on gaming, and the memory consumption has been reduced by 118MB.
Unity: 579MB vs Cinnamon: 461MB
Hope this helps.
Hi there thanks for this very well done.
I also found these should be able to be removed:
