Sei que há muito material relacionado a esses problemas, mas muito parece desatualizado e nada parece estar funcionando para a minha situação:
- ThinkPad W520 (chipset Intel 3000 e Nvidia 1000M)
- SO: Ubuntu 12.04.3.
- Configuração da placa gráfica do BIOS:
Optimus
- Detecção automática do BIOS OS Optimus:
disabled
Usei o wiki do Bumblebee abaixo para instalar e configurar o Bumblebee: https://wiki.ubuntu.com/Bumblebee#Installation
Depois de definir meu BusID para a placa gráfica como "PCI: 01: 00.0" (consulte os arquivos de configuração abaixo), sou capaz de executar optirun firefox
e os testes do virtualgl como optirun glxspheres64
e glxspheres64
. Portanto, acredito que tudo esteja bem com a instalação do Bumblebee, exceto que não consigo conectar ao meu monitor externo (via VGA). Algumas ideias em como fazer isso? O W520 possui o VGA (e o DisplayPort) conectados à placa Nvidia, conforme descrito por Zachary Sunberg:
http://zachstechnotes.blogspot.com/2012/04/post-title.html
Portanto, acredito que isso torne as coisas um pouco complicadas ao tentar conectar o VGA a um monitor externo. Acredito que tenho que usar um servidor / clone de tela, descrito nas minhas tentativas documentadas abaixo:
Eu tentei o seguinte post para configurar os monitores externos,
http://hillspcworld.com/forum/index.php?topic=2.0
Porém, a reinicialização após a etapa 7 causa uma falha total do sistema operacional (tela preta após o carregador de inicialização que diz "Não foi possível gravar bytes: tubo quebrado"). Eu acredito que isso se deve ao fato do servidor xorg interromper meu sistema de alguma forma.
Tentei uma abordagem semelhante no tutorial a seguir, mas tive a mesma falha do (1) durante a reinicialização após a instalação do xorg-dev:

A partir de agora, estou me perguntando para onde ir a partir daqui. Tenho algumas pistas abaixo, alguma idéia sobre qual é o problema ou o que posso fazer? Existe uma sugestão melhor? http://zachstechnotes.blogspot.com/2012/04/post-title.html

Além disso, aqui estão alguns dos meus arquivos (deixe-me saber se há uma configuração melhor - a única alteração que fiz foi descomentar o "BusID PCI: 01: 00.0" no xorg.conf.nvidia

# If the X server does not automatically detect your VGA device,
# you can manually set it here.
# To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
# as you see in the commented example.
# This Setting may be needed in some platforms with more than one
# nvidia card, which may confuse the proprietary driver (e.g.,
# trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.
BusID "PCI:01:00:0"
# Setting ProbeAllGpus to false prevents the new proprietary driver
# instance spawned to try to control the integrated graphics card,
# which is already being managed outside bumblebee.
# This option doesn't hurt and it is required on platforms running
# more than one nvidia graphics card with the proprietary driver.
# (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
# If this option is not set, the new Xorg may blacken the screen and

Obrigado.

não quis dizer #arandar
apt-get install arandar
, abra o arander e configure-o. Se isso funcionar, basta copiar a configuração e instalar os mesmos drivers.
