Ubuntu Desktop comes with GNOME as the default desktop environment. Ubuntu Desktop also has the necessary GNOME applications and tools, configured for the Ubuntu experience.
If you're already running Ubuntu, you can still install KDE, or even the complete Kubuntu desktop on top of your Ubuntu or GNOME desktop. It can be done by installing the appropriate meta package via apt at the terminal.
Steps to install KDE Plasma on Ubuntu and Debian:
- Launch terminal.
