Display Manager Tasks

AC

A display manager is a software component in the Linux system that provides an interface for users to log in and start a desktop environment. It is responsible for managing the X server and presenting the user with a graphical login prompt, which includes a list of available desktop environments to choose from.

The tasks handled by a display manager such as XDM or KDM include:

A. Start and prepare the desktop environment for the user: The display manager starts the X server and the desktop environment selected by the user, usually through a configuration file that defines the default desktop environment.

C. Handle the login of a user: The display manager prompts the user for their username and password, verifies them against the system's user database, and grants or denies access based on the credentials provided.

D. Lock the screen when the user was inactive for a configurable amount of time: The display manager can be configured to automatically lock the screen after a certain amount of time of user inactivity, thereby protecting the user's data and privacy.

B. Configure additional devices like new monitors or projectors when they are attached: This task is not typically handled by a display manager, but rather by the desktop environment or the underlying system utilities that manage hardware devices.

E. Create an X11 configuration file for the current graphic devices and monitors: This task is also not typically handled by a display manager, but rather by the X server or the system's graphical utilities that detect and configure the available hardware devices.

In summary, the two correct answers are A. Start and prepare the desktop environment for the user, and C. Handle the login of a user.
