Bueno, he estado probando estas cosas y otras que me ha contado Redy por teléfono pero no hay grandes cambios.
Básicamente hemos borrado el módulo nouveau que salía con lsmod y añadido un modprobe nvidia-current después de desinstalar y volver a instalar el paquete y la única diferencia es que ahora no da el error del plymouth, pero se para en el mismo sitio.
Pasando a una consola de texto (alt-F2) y haciendo un startx se queja con un "Fatal error: no screens found".
En principio, esto arranca si en el xorg.conf hay una entrada para la Intel, sea única o conjunta con una nvidia/nouveau, pero arranca siempre con la gráfica Intel.
Este es un xorg de los que arrancan, el de ahora. He probado a quitar la Intel, a cambiarles el número de display... pero el resultado es el mismo.
