Problema con configuración de X

mira a ver si tienes una copia de seguridad de tu xorg.conf (debe llamarse xorg.con.unarristramuylargadenúmeros o xorg.conf.BACKUP). Sustituye el xorg.conf por la copia de seguridad y ya deberían arrancarte las X.

Pues he probado a hacerlo y sigue sin funcionar. He probado a instalar los ultimos drivers de la página de nvidia y editado el xorg (para eliminar manualmente las líneas que introduje para hacer funcionar el beryl) y tampoco se soluciona, no sé que hacer ya.

2 cosas:

1. ¿Qué tarjeta gráfica tienes?
2. Pega aquí tu xorg.conf, por favor.

PD: Si tienes una copia de seguridad del xorg, pégala también.

Bueno aquí va el xorg.conf:

Y el xorg.conf.backup adjunto:

La tarjeta gráfica es una 6600, no pensé que fuese relevante el modelo.
Saludos.
