How to change the default Ubuntu desktop environment?

Ubuntu comes with its own desktop environment called Unity, but you can install and use other desktop environments like GNOME, KDE, XFCE, etc. Here's how you can change the default Ubuntu desktop environment:

1. Install the desktop environment you want to use:

For example, to install the GNOME desktop environment, open a terminal and type the following command:

1

sudo apt-get install ubuntu-gnome-desktop

1. Once the installation is complete, log out of your current session.
2. Click on the gear icon located on the top right corner of the login screen, and select the new desktop environment from the list of available options.
3. Enter your login credentials, and the new desktop environment will be loaded.
4. If you want to make the new desktop environment the default one for future sessions, select the gear icon again, and choose "Set as default" option.

That's it! You have successfully changed the default Ubuntu desktop environment.
