CompTIA Linux+ XK0-006 (V8) Practice Question

The correct answer is a display manager. A display manager, also known as a login manager, is a graphical program that starts at the end of the boot process. Its primary roles are to display a graphical login screen, authenticate users, and manage graphical display servers and user sessions by launching the chosen desktop environment or window manager.

• The X Server (or a Wayland compositor) is the underlying graphical server that draws windows and handles input/output, but it does not manage the login process itself.
• A window manager is responsible for controlling the placement and appearance of windows within a graphical desktop environment, but it only becomes active after a user has logged in.
• The initial RAM disk (initrd) is used much earlier in the boot process to load a temporary root filesystem into memory, which helps in loading necessary kernel modules before the main root filesystem is mounted.
