Which of the following are tasks handled by a display manager like XDM or KDM? (Choose TWO correct answers.)

After successful user authentication, a display manager is responsible for starting the user's graphical session, which includes initiating and preparing the chosen desktop environment (e.g., GNOME, KDE, Xfce).

Configuring additional display devices such as new monitors or projectors is typically handled by the desktop environment itself or specific display configuration utilities (e.g., `xrandr`, display settings in control panels), not directly by the display manager.

The primary role of a display manager is to present a graphical login screen, handle user authentication against the system, and manage the user's login session.

Screen locking due to user inactivity is a feature provided by the desktop environment's screen saver or power management components, not a direct task of the display manager.

Creating X11 configuration files for graphics devices is generally managed by the Xorg server's auto-detection mechanisms, graphics drivers, or system-wide configuration utilities, not by the display manager.
