Então eu tenho um laptop 510p da Lenovo, com placa gráfica Intel HD 4600 integrada, mais 2 GeForce GT 755M-s, uma das quais está no ultrabay e, portanto, é removível. Estou executando o Lubuntu 13.10. Eu uso o driver proprietário nvidia (331).
Eu instalei o bumblebee, e parece estar funcionando bem quando a placa de vídeo removível não está presente, no entanto, se eu conectar o ultrabay, coisas estranhas acontecem.
De alguma forma, parece que o cartão de intel integrado não é captado, e eu não tenho ideia do que acontece realmente.
Alguns registros:

Então a grande questão é : isso é normal? Eu nunca tive uma máquina como antes (também nunca usei bumblebee antes), então eu realmente não sei o que esperar.
No entanto, a situação parece estranha, e se possível, eu gostaria de usar o cartão de intel ambos os casos e seria bom não ter que remover o segundo VGA quando eu quero um linux funcionando bem. Existe uma maneira por exemplo para desativar / ocultar completamente o optibay VGA? Eu não gostaria de usá-lo no Linux de qualquer maneira.
