In the /usr/share/doc/lightdm/lightdm.conf provided with Ubuntu 11.10, there is a chapter about VNC:
# VNC Server configuration
#
# enabled = True if VNC connections should be allowed
# port = TCP/IP port to listen for connections on
#
[VNCServer]
#enabled=false
#port=5900
#width=1024
#height=768
#depth=8
However, it does not say anything about that you need to manually install a matching VNC-server. This should be noted somewhere.
