Select the THREE entries in the following list that are complete desktop environments rather than a single component of one.
LPIC-1 Exam 102-500, objective 106. User interfaces and desktops easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
The options
Choose 3.
Correct Xfce
Correct. Xfce ships a window manager, a panel, a file manager, a settings manager and a session manager as one coherent environment, and is chosen for being lighter than GNOME or Plasma.
Not correct Mutter
Wrong. Mutter is the window manager and compositor used by GNOME. It places, decorates and composites windows, but supplies none of the panels, file manager or settings tools that make an environment.
Correct GNOME
Correct. GNOME is a full environment built on the GTK toolkit, with GNOME Shell as its interface, Nautilus as its file manager and GDM as its usual display manager.
Correct KDE Plasma
Correct. Plasma is KDE's desktop environment, built on Qt, with KWin as its window manager and Dolphin as its file manager.
Not correct Nautilus
Wrong. Nautilus is GNOME's file manager, one application within that environment. Running it alone gives you a file window and nothing else.
Not correct Wayland
Wrong. Wayland is a display protocol that an environment's compositor implements. It is a layer beneath the desktop, in the position X11 occupies for an Xorg session.
Why
A desktop environment is the whole set — window manager, panel or shell, file manager, settings tools and session management — presented as one product. The names candidates are expected to place are GNOME, KDE Plasma, Xfce and LXDE/LXQt as environments; Mutter, KWin and Openbox as window managers; GDM, SDDM and LightDM as display managers; and X11 or Wayland as the protocol underneath all of them. Sorting an unfamiliar name into one of those four layers is the skill being tested.
