Sé que hay mucho material sobre estos problemas, pero gran parte parece anticuado y nada parece funcionar para mi situación:
- ThinkPad W520 (chipset Intel 3000 y Nvidia 1000M)
- SO: Ubuntu 12.04.3.
- Configuración de la tarjeta gráfica del BIOS:
Optimus
- Detección automática del BIOS OS Optimus:
disabled
Usé el wiki de Bumblebee a continuación para instalar y configurar Bumblebee: https://wiki.ubuntu.com/Bumblebee#Installation
Después de configurar mi BusID para la tarjeta gráfica en "PCI: 01: 00.0" (ver los archivos de configuración a continuación), puedo ejecutar optirun firefox
y las pruebas de virtualgl como optirun glxspheres64
y glxspheres64
. Entonces, creo que todo está bien con la instalación de Bumblebee, excepto que no puedo conectarme a mi monitor externo (a través de VGA). ¿Alguna idea sobre cómo hacer esto? El W520 tiene el VGA (y DisplayPort) conectado a la tarjeta Nvidia, como lo describe Zachary Sunberg:
http://zachstechnotes.blogspot.com/2012/04/post-title.html
Por lo tanto, creo que esto hace que las cosas sean un poco difíciles al intentar conectar el VGA a un monitor externo. Creo que tengo que usar un servidor / clon de pantalla, descrito en mis intentos documentados a continuación:
Intenté la siguiente publicación para configurar los monitores externos,
http://hillspcworld.com/forum/index.php?topic=2.0
Pero reiniciar después del paso 7 hace que el sistema operativo se bloquee por completo (pantalla negra después del gestor de arranque que dice "No se pudieron escribir bytes: tubería rota"). Creo que esto se debe a que el servidor xorg interrumpe mi sistema de alguna manera.
Intenté un enfoque similar en el siguiente tutorial, pero tuve el mismo bloqueo que en (1) durante el reinicio después de instalar xorg-dev:

A partir de ahora, me pregunto a dónde ir desde aquí. Tengo un par de pistas a continuación, ¿alguna idea sobre cuál es el problema o qué puedo hacer? ¿Hay alguna sugerencia mejor? http://zachstechnotes.blogspot.com/2012/04/post-title.html

Además, aquí están algunos de mis archivos (avíseme si hay una mejor configuración; el único cambio que hice fue descomentar el "BusID PCI: 01: 00.0" en el xorg.conf.nvidia
