Ubuntu and Xubuntu are operating systems based on Debian Linux. The operating systems are very similar except they use different default desktop environments. Xubuntu uses the lightweight XFCE desktop environment, while Ubuntu uses the more processor-taxing GNOME environment. You can switch between the desktop environments by downloading and installing software from within Xubuntu. This enables the user to switch environments without having to change the current Xubuntu installation or migrate any files to a new operating system. Writer Bio
