Desktop Environment (DE)
The Desktop Environment is the complete graphical interface that you see and interact with after logging into your Linux system. It defines the overall look, feel, and behavior of your desktop—from the taskbar to the window decorations, file explorer, app launcher, and system settings.
“The Desktop Environment is the entire outfit your system wears—it controls the style, layout, and tools you interact with every day.”
- The DE is not the OS itself, but a graphical shell built on top of it.
- You can install multiple DEs on the same system and switch between them at login.
- Each DE bundles its own default apps and configurations, but you can mix and match.
