Linux System

A display manager logs you in while a window manager governs windows, panel, menus, dash interfaces and core applications. Many of these items are bundled together to make a desktop environment.

Some Linux distributions ship with just one desktop environment (although others are available in the software repositories), while others offer different versions of the distribution fine-tuned for different desktop environments.

Common desktop environments include Cinnamon, GNOME, Unity, KDE, Enlightenment, XFCE, LXDE and MATE.

Cinnamon is a more conventional desktop environment that looks much like Windows 7, with a panel at the bottom, a menu, system tray icons, and quick launch icons. 

GNOME and Unity are fairly similar. They are modern desktop environments that use the concept of launcher icons and a dashboard-style display for picking applications. There are also core applications that integrate well with the overall theme of the desktop environment.

KDE is a fairly classic-style desktop environment with many custom features and a core set of applications that are all highly customizable.

Enlightenment, XFCE, LXDE, and MATE are lightweight desktop environments with panels and menus.
