ERROR: The Nouveau kernel driver is currently in use by your system. This driver is incompatible with the nvidia driver, and must be disabled before proceeding. Please consult the NVIDIA driver README and your Linux distribution´s documentation for details on how to correctly disable the Nouveau kernel driver.

For some distributions, Nouveau can be disable by adding a file in the modprobe configuration directory. Would you like nvidia-installer to attempt to create this modprobe file for you?

One or more modprobe configuration files to disable Nouveau, have been written. For some distributions, this may be sufficient to disable Nouveau; other distributions may require modification of the initial ramdisk. Please reboot your system and attempt NVIDIA driver instalation again. Note if you later wish to reenable Nouveau, you will need to delete these files:
/etc/modprobe.d/nvidia-installer-diable-nouveau.conf

“Ubuntu 12.10 ha sido liberado sin el paquete "linux-headers-generic", que trae las cabeceras genéricas del núcleo o Kernel Linux.

Esto no es un problema para un uso normal de Ubuntu, a menos que necesitemos compilar un módulo del kernel y aquí entra en juego la instalación de los controladores privativos.

Al instalar el controlador privativo se configura el módulo de la gráfica mal, al faltar los headers y esto hace que la gráfica (Xorg) se "rompa", provocando diversos errores (pantalla negra, pixelada, líneas moviéndose, …). Ubuntu responde que el paquete ya no viene instalado por defecto y que deja en manos del usuario instalarlo o no. El problema es que al instalar el controlador privativo desde controladores adicionales no te avisa que necesitas como dependencia el paquete linux-headers-generic”

“El problema en cuestión es la falla del driver propietario de Nvidia al colocar la resolución correcta para nuestro monitor (en la mayoría de los casos, porque no es capaz de leer correctamente la EDID del mismo), con otras placas de video este problema no surge, debido a que los demás drivers usan XRandR, una extensión del X Server que permite manejar los temas de resolución, y que tiene mejor autodetección de hard gracias al uso de HAL.”
