Explanation

A display manager's two core jobs are presenting the graphical login screen and, after credentials are verified, launching the selected desktop environment (session) for that user - making B and E the correct answers.

Why the distractors are wrong:

• A - Hotplug detection and configuration of new monitors/projectors is handled by the kernel (udev) and tools like xrandr, not the display manager.
• C - Generating or writing xorg.conf is the job of X -configure or distribution-specific tools (e.g., nvidia-xconfig), not the display manager.
• D - Screen locking on inactivity is managed by a screensaver/locker daemon (e.g., xscreensaver, xss-lock, or the desktop environment itself), not the display manager.

Memory tip: Think of a display manager as a digital doorman - it greets you at the door (login screen) and escorts you to your room (starts your desktop). Everything else - redecorating, locking up, or adding new furniture - is someone else's job.
