Estou executando uma área de trabalho 14.4LTS. Quando o sistema inicializa, a rede é configurada com base nas configurações /etc/network/interfaces . Eu posso pingar ou acessar a caixa remotamente via ssh.
Quando o usuário local efetua login via interface gráfica, ele tem a rede eth0 em execução por cerca de 10 a 30 segundos (o ícone com fio é inicialmente visível) e o sistema remove / desativa o dispositivo e não há rede disponível um ícone de wifi vazio é exibido. Eu tenho um dispositivo Wi-Fi usb que foi configurado no passado, mas não está conectado ao computador.
Se eu abrir um termo e executar sudo ifconfig eth0 up , a rede estará ativada (endereço estático) e o ícone do NetworkManager será alterado para o ícone com fio e anotará que a interface ifupdown está conectada.
Algumas mensagens de registro relevantes:

e meu arquivo NetworkManager.conf:
# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in

A conexão com fio é usada para iniciar por conta própria; Eu acredito que isso só começou quando eu temporariamente tive que adicionar uma conexão wi-fi para a caixa enquanto a minha rede com fio estava em baixo. Eu tenho, antes de postar aqui, removi minha configuração wifi e ainda tenho o mesmo problema com a conexão com fio "indo embora".
Algo deu errado. Alguma ideia? Parece que não consigo ligar este problema específico apenas de utilizador a outros problemas semelhantes na Web. A rede é apenas para baixo para a maioria das pessoas com problemas semelhantes, tudo ou nada. Para o meu sistema, parece ser específico do usuário.
Conteúdo adicional
Seguindo o meu comentário / resposta abaixo, aqui está o meu arquivo de interfaces atualizado. Eu também adicionei apenas a opção hotplug durante minhas próprias fases de solução de problemas porque achei que era um bom recurso caso eu tivesse que trocar os cabos por qualquer motivo. Eu removi a linha apenas para seguir o conselho de algumas pessoas. Não fez diferença.

Conteúdo adicional # 2
Acabei de perceber que, embora a rede estivesse em execução, depois de usar o comando ifconfig e a resolução de DNS estivesse funcionando, nenhum dos meus aplicativos de rede se conectaria à Internet. Isso inclui Skype, email (Thunderbird), navegação na web e PIA. Eu configurei o managed de volta para true no NetworkManager e reiniciei. Todos os meus aplicativos funcionam agora. Acho que isso aconteceu comigo quando tentei esse método sozinho antes de vir aqui em busca de ajuda. Então, o que poderia estar acontecendo agora? Antes de "consertar" o NM como indicado, eu poderia fazer ping no meu roteador e fazer um nslookup / dig a partir da linha de comando sem um problema. Ugh. Alguma ideia? Isso parece um pouco ... irregular. Esta não é a minha área de trabalho principal, por isso não tentei aplicativos depois das alterações mencionadas anteriormente.
Estas parecem ser as mensagens de log relevantes para a interface do syslog quando eu reconfigurei / reiniciei o NM:
