Eu não sou um usuário completamente novo do Ubuntu / Linux, mas ainda sou de longe um novato.
Eu também não tenho 100% de certeza de que todas as informações são necessárias (e / ou como obtê-las), então, por favor, deixe-me saber o que está perdendo.
Meu problema é que, ocasionalmente, ao inicializar, depois que o GRUB aparece, ele pisca algumas vezes e vai para uma tela em branco / preta. A tela está claramente acesa e acesa, mas não mostra nada. Nenhum cursor, nada. Ele irá reproduzir o som de inicialização, mas eu tenho que fazer um desligamento e ligá-lo completamente de volta para poder fazer o login.
Eu acho estranho porque eu tenho um laptop muito mais antigo (um Lifebook da Fujitsu) que tem muitos outros problemas, mas eu nunca tive esse problema.
Eu também notei que o processo de inicialização padrão pelo qual o Ubuntu aparentemente está passando não é exibido para mim. Eu entendo que há uma tela que é exibida durante a inicialização - eu nunca a vejo. Eu consistentemente, após o grub, vejo uma tela preta que pisca. Eventualmente, ele normalmente carregará para uma tela em branco com o cursor e, em seguida, a tela de login. Outras vezes, é a tela preta em branco que está ligada.
Eu não vi isso acontecer depois que voltei do modo de suspensão. Só parece acontecer quando eu estou começando.
Eu tenho uma inicialização dupla com o Windows 10, mas não tenho certeza se tem alguma relevância. Além disso, peço desculpas pelo tamanho, mas não sei como colocar todos os resultados do LSHW em sua própria janela de rolagem separada nesse post.
