# This module implements a terminal service based on ‘x11vnc’. It
|

# listens on port 5900 for VNC connections. It then presents a login
|
||
# screen to the user. If the user successfully authenticates, x11vnc
|
||
# checks to see if a X server is already running for that user. If
|
||
# not, a X server (Xvfb) is started for that user. The Xvfb instances
|
||
# persist across VNC sessions.
