Is there any way to stop NetworkManager applet and switch to manual configuration of /etc/network/interfaces?

If you manually configure an interface in /etc/network/interfaces, NetworkManager will not manage it. For example, add the following to interfaces file:

iface eth0 inet dhcp

Then restart NM service (sudo service network-manager restart), now NM appplet will say that device is not managed.

    But NetworkManager will feel perfectly free to rewrite the interfaces file, throwing away all your additions, so be sure and have a backup handy.

  • @ubfan1 Not, really. NetworkManager doesn't write config to the interfaces file. I added iface eth0 inet dhcp to my interfaces and after sudo service network-manager restart NM says the wired network interface is unmanaged and I'm not allowed to interact with it via NM.

to stop network manager

sudo /etc/init.d/network-manager stop

To stop it from managing eth0 on next reboot, edit /etc/network/interfaces like so, changing the addresses to suit your needs

auto eth0
iface eth0 inet static
    address 10.0.1.69
    netmask 255.255.255.0
    gateway 10.0.1.1
    dns-search example.com
    dns-nameservers 10.0.1.8 10.0.1.9

    Upon reboot, NM will start again. If you really want it to go away forever, remove it and reboot.
