Problemas
reboot não funcionará (acho que há algo a ver com a parte de gerenciamento de energia ...) Este é apenas um dos sistemas operacionais instalados no Ubuntu 16.04. E está tudo bem no assistente de instalação .

DISTRIB_DESCRIPTION="Ubuntu 16.04.1 LTS"
Depois que eu reiniciar do disco rígido, eu posso ver o menu grub, depois de selecionar 'ubuntu', a tela ficou escura, diz: "sem sinal".
O sistema é acessível a partir da rede remota, por isso posso retirar esses registros de kern.log .
Estas são as linhas suspeitas de kern.log
