Desempenho degradado na inicialização após a instalação do Gnome Desktop

0

Eu instalei o Ubuntu 14.04 através de um CD mínimo. Parecia uma janela de terminal, então eu fiz: apt-get install gnome e baixei um monte de coisas. Então eu reiniciei e criei uma conta.

Tem levado muito tempo para o Ubuntu, eu recebo uma tela roxa com quatro pontos e eles acendem e apagam e, em seguida, ele diz que está tentando fazer conexões de rede. em seguida, espere até 60 segundos para conexões de rede e, finalmente, ele carrega, mas leva o que parece ser 10 minutos.

Eu não sei muito sobre Ubuntu ou Linux e não sei o que fazer. Abaixo está minha dmesg.txt

A primeira coisa que vejo na saída que você postou é esta:
IPv6: wlan0: IPv6 duplicate address fe80::5a94:6bff:fe22:3680 detected!
o que teoricamente não deveria acontecer, já que os endereços ipv6 usam endereços mac teoricamente únicos como parte da estrutura de endereço. Então, de alguma forma, você foi alvo de uma anomalia estatística, seja ela produzida ou acidental.

De qualquer maneira, a paralisação das interfaces de rede causará a parada da inicialização até que um tempo muito mais longo do que o tempo limite normal seja ultrapassado e a inicialização seja retomada.
