_Description: Default display manager:
A display manager is a program that provides graphical login capabilities for
the X Window System.
Only one display manager can manage a given X server, but multiple display
manager packages are installed. Please select which display manager should
run by default.
Multiple display managers can run simultaneously if they are configured to
manage different servers; to achieve this, configure the display managers
accordingly, edit each of their init scripts in /etc/init.d, and disable the
check for a default display manager.
