Here’s How to Find Out Which Desktop Environment You are Using

Whether you’re troubleshooting an issue, customizing your interface, or just curious, knowing which desktop environment (DE) you’re using on Linux can save you time and confusion. But if you’re not sure how to check, you’re not alone. Here’s how to figure it out quickly and clearly.

What Is a Desktop Environment?

A desktop environment is the graphical layer on top of your Linux system. It includes the panel, window manager, file manager, system settings, and more. Popular DEs include GNOME, KDE Plasma, XFCE, Cinnamon, MATE, and LXQt. Each has its own look, feel, and tools.

Method 1: Use the Terminal

This is the fastest way and works across most distributions.

Run this command:

echo $XDG_CURRENT_DESKTOP

This will usually return something like:

GNOME
KDE
X-Cinnamon
XFCE
MATE

If that doesn’t work, try:

echo $DESKTOP_SESSION

Or:

echo $GDMSESSION

These environment variables often give similar information.

Method 2: Use `neofetch`

If you have neofetch installed (or want to install it), this tool shows a quick summary of your system, including the desktop environment.

Install it (if needed):

sudo apt install neofetch   # Debian/Ubuntu
sudo dnf install neofetch   # Fedora
sudo pacman -S neofetch     # Arch

Then run:

neofetch

Look for the “DE” field in the output.

Method 3: Check the System Info GUI

If you prefer not to use the terminal:

GNOME: Go to Settings > About — you’ll see “GNOME” listed there.
KDE: Open Info Center or System Settings, then go to About System.
XFCE: Open Settings > About Me or About XFCE.
Cinnamon/MATE/LXQt: Each has its own version of a system information window — check your main settings app.

Final Tip: DE ≠ Window Manager

Don’t confuse your desktop environment with your window manager (like Mutter, KWin, or Openbox). The DE is the full package; the window manager is just one part of it.

Why It Matters

Knowing your desktop environment helps when you’re:

Installing compatible themes or extensions
Following DE-specific tutorials
Debugging display or behavior issues
Explaining your setup in forums or support chats

Now that you know how to find it, you’re in a better position to take control of your Linux experience.
