I have Network Manager on my 14.04 laptop. It currently manages the networking.

Unfortunately, I don't want Network Manager to manage the Ethernet card, eth0, and I just want it to handle the wireless wlan0 card.

I'd like to let the system (dhclient, etc.) handle my Ethernet, not Network Manager.

Is it as simple as turning the eth0 interface over to the kernel via /etc/network/interfaces and adding an eth0 stanza, or is there something else I need to do?

    If you add eth0 to /etc/network/interfaces, NM will stop managing this interface.

  • @Pilot6 add that as an answer please? (I ask whether it's that simple or not)

Network Manager does not manage interfaces that are mentioned in /etc/network/interfaces.

That sometimes confuse people. If you add all interfaces there, NM indicator will not appear at all.
