Questão Tela Ocasional em Branco (preta, mas ligada) - Ubuntu 14.04.3 LTS (x86 64 bits)


Eu não sou um usuário completamente novo do Ubuntu / Linux, mas eu 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. isto vai reproduzir o som de inicialização, mas eu tenho que fazer um desligamento forte 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 tomei nota que o processo de inicialização padrão que 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 um dual-boot 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.

Caso não seja mencionado lá, eu estou em um Lenovo G50-45. Tudo bem quando eu inicializo o Windows, geralmente bem quando eu inicializo o Ubuntu.

ATUALIZAÇÃO 9-2-2015

Verifique o driver da placa gráfica. Abra o terminal e digite:

ubuntu-drivers devices  

A saída de ubuntu-drivers devices mostrará uma lista de drivers de placas gráficas dos repositórios do Ubuntu que são compatíveis com seu laptop. Eu esperaria que fglrx seria o driver proprietário da placa de vídeo para instalar em uma Radeon APU A4-6000 com R2 Graphics.

O driver de placa de vídeo xserver-xorg-video-ati está listado como recomendado porque ele já está instalado no Ubuntu 14.04 por padrão. Se você instalar o driver da placa de vídeo proprietária fglrx, o Ubuntu usará o fglrx sem desinstalar o xserver-xorg-video-ati, para que você ainda possa inicializar com o driver da placa gráfica xserver-xorg-video-ati no caso de ter um problema Inicializando com fglrx.

Para instalar o fglrx eo Catalyst Control Center para o acelerador gráfico AMD Radeon (fglrx-amdcccle), abra o terminal e digite:

sudo apt install fglrx fglrx-amdcccle  
sudo reboot  

O fglrx não é mais suportado no Ubuntu 16.04 e posterior. No Ubuntu 16.04 e posteriores, os processadores gráficos AMD usam o driver gráfico AMD de código aberto integrado por padrão. Alternativamente, você pode baixar a versão estável mais recente do driver gráfico proprietário da AMD a partir do site oficial da AMD.

Obrigado. Corri isso e editei minha pergunta original com os resultados. Eu li, agora mesmo, que fglrx é um driver proprietário da ATI, mas os resultados recomendam o driver do xorg. Devo instalar o driver do xorg em vez disso? Só está recomendando porque é open source? - Heather B
Eu editei minha resposta com uma resposta ao seu comentário. - karel
Muito obrigado por toda sua ajuda. Eu instalei o driver fglrx e eu reiniciei várias vezes e não vi a tela em branco novamente, e agora vejo a tela roxa e a tela inicial enquanto estou inicializando, então tudo parece ter funcionado. - Heather B
