Comment 93 for bug 762203

11.10 clean install.

Sporadically takes ages to shutdown and sometimes never. Plymouth just displays progress dots.

Tried this and it seem to make shutdown much faster. Add this line, stop on runlevel [06], to this file.
gksu gedit /etc/init/network-manager.conf

# network-manager - network connection manager

# The Network Manager daemon manages the system's network connections,
