I've got two Ubuntu laptops (both 10.10).
One is a new Maverick install and the other has been upgraded many times since 9.04.

On the latter, setting up a custom script hook in /etc/NetworkManager/dispatcher.d/ worked instantaneously.

However, on the older laptop, I can't get nm-dispatcher to get called, or at least to execute its hooks.

I've tried to run

NetworkManager --no-daemon -log-level=DEBUG

But there is no mention of nm-dispatcher.

How can I

1. Have a look at the source (I looked into the git repo but could not find anything.

2. find why the nm-dispatcher never gets called.
