Estou tentando instalar o Ubuntu 17.04 (Zesty) no meu Mac Pro (Lixeira).
Sem o out nomodeset nos parâmetros de inicialização, o X.Org é finalizado na inicialização.
O display alterna entre um trabalho tty2 e um corrompido tty a cada 3 segundos.
A cauda de /var/log/Xorg.0.log é…

Onde há duas placas de vídeo idênticas, o mesmo driver não deve ser usado para ambos?
Ao inicializar com nomodeset nos parâmetros de inicialização, posso fazer o x.org rodar e permitir que eu abra uma janela de terminal.
Ao fazer isso e executar lspci -k | grep -EA3 'VGA|Display' , obtenho

Além disso, a expressão /var/log/syslog da palavra "segfault" aparece 32 vezes, "error" 92 vezes, "fail" 195….
Isso é normal?

Esse mesmo problema ocorre em 16.04.3 LTS, mas fica estranho.
A tela muda para branco e para trás 3 vezes mais rápido do que ok por 1,5 segundos.
O teclado só responde a chaves mágicas quando NÃO está em branco.
A tecla mágica U pára de piscar e estabiliza o sistema quando em tty.
A parte estranha é que se eu repetidamente tentar reiniciar o sistema, ele irá inicializar em um sistema operacional bem uma vez a cada 4 ou 6 tentativas?
Como você depura isso?
