How to disable Network Manager on Linux

First Check if NetworkManager is running on Ubuntu / Debian

Usually you should be using NetworkManager by default (Ubuntu 14.04), just in case you want to be sure, use this command to verify:

dpkg --get-selections | grep network-manager

In case there is some output like:

network-manager install

it is installed, if there is nothing returned, you are probably using a different network managing daemon. It would be possible that network manager is installed but inactive. Lets check if its running the hard way:

ps aux | grep network-manager

If thats returning something different than itself, you can be sure using the NetworkManager in Ubuntu / Debian.
