Instalei o Ubuntu 16.04 em um Notebook Samsung, mas não consigo inicializar sem desabilitar o acpi. Eu adicionei acpi=off a GRUB_CMDLINE_LINUX_DEFAULT em /etc/default/grub e atualizei as opções do grub com update-grub . Agora toda vez que eu tento desligar a máquina, ela para e eu tenho que desligá-la diretamente no botão liga / desliga. Isso é um problema de driver? Como posso debugar e descobrir qual hardware está falhando? Eu suspeito que isso esteja relacionado à minha placa de vídeo.
