Actualmente estoy ejecutando Ubuntu 14.04 con una gpu GTX 780m en mi computadora portátil y usando controladores nvidia-331 con bumblebee.
No pude controlar el brillo de mi pantalla, pero luego decidí seguir algunos consejos en Internet y agregué las siguientes líneas al archivo/usr/share/X11/xorg.conf.d/20-intel.conf:
Section "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
Después de eso pude controlar el brillo, todo muy bien. El problema es que, después de eso, bumblebee no funciona, por ejemplo, al intentar abrir Steam usando primusrun aparece este mensaje:
Running Steam on ubuntu 14.04 64-bit

Si pruebo optirun steam, eso es lo que aparece:
[ 6051.673074] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Server terminated successfully (0). Closing log file.
[ 6051.673179] [ERROR]Aborting because fallback start is disabled.
Buscando en Internet, alguien señaló que al agregar este código:
Section "Screen"
Identifier "Default Screen"
Device "DiscreteNvidia"
EndSection
Al encabezado del archivo/etc/bumblebee/xorg.conf.nvidiafuncionaría, pero no fue así. Después de aplicar estas modificaciones, cuando intentovapor primusrun, eso es lo que obtengo:

Entonces, ¿tienes alguna idea de cómo puedo hacer que funcionen tanto el control de brillo como el abejorro?
¡Gracias de antemano!
