How can I completely remove NetworkManager?

Question

I want to disable NetworkManager entirely, and have my eth0 and wifi connections unmanaged. My eth0 on my main linux box is unmanaged and I have no issues with it, I want to do the same to my other linux boxes all running Ubuntu 12.04 LTS, basically I want to kill Network Manager and never see any trace of it again.

First edit /etc/network/interfaces so that the ifup utility can be used to configure eth0 once NetworkManager is gone.

Remove NetworkManager from the system

sudo apt-get purge network-manager

Configure eth0 using ifup.

sudo ifup eth0

It might be worth it to disable it, configure your alternate setup, and then uninstall it.

sudo apt-get purge network-manager

/etc/resolv.conf and /etc/network/interfaces must both be edited for a manual connection otherwise you will be left without full network capability.

I don't have 50 rep points to comment, so I'll add some info as an answer that may be helpful. On a Surface Pro 3 with Ubuntu 14.04 installed, Giving this command:

killall -STOP NetworkManager

made a dramatic improvement in RTP-over-wireless streaming applications. NM can be restarted with -CONT parameter. More details here:

Disable / Enable Periodic Wireless Scans

For the SP3 there are other settings required, including net.core.xxx items, and to maintain optimum performance it should remain plugged in. Likely this info applies to other tablets with Ubuntu also.
