Exam LX0-104 topic 2 question 4 discussion

A display manager is a software program that manages the graphical login and user authentication process for a computer system. The purpose of a display manager is to provide a graphical interface for users to log in and start a session, as well as to manage the launch of the desktop environment or window manager. Display managers also handle user authentication, meaning that they verify the credentials of a user before granting access to the system. Some display managers may also offer additional security features such as locking the screen after a period of inactivity or when the user switches to another virtual terminal. Display managers also provide a way for users to choose the desktop environment or window manager they wish to use for their session, or to customize various settings such as screen resolution, color depth, and display orientation. In general, the purpose of a display manager is to provide an attractive and user-friendly interface for managing user logins and starting desktop environments, as well as to provide a centralized mechanism for controlling the user environment.
