Hola a todos,
hace muchisimo que no posteaba nada por que siempre encontraba la respuesta en el foro o google pero ahora estoy muy perdido, necesitaba algunas cosas que venian en el nuevo kernel asi que lo compile e instale en mi sistema sin muchso problemas, solo algunas cosas faciles de resolver.
Como sabia que no iba a andar el modulo nvidia despues de compilar un nuevo kernel, lo volvi a instalar desde el instalador propietario sin muchos problemas.
Pero al querer iniciar X hace unos intentos y se cuelga indefectiblemente. Probe mil cosas y ninguna funciono. Parece ser algo relacionado con GLX.
Una cosa que me di cuenta, y que me parece extraño, es que si desinstalo el driver, lo instalo nuevamente e inicio gdm (uso gnome) inicia sin problemas, pero al resetear deja de hacerlo.

Bueno les pego el contenido de xorg.conf y de la salida en syslog, lo mas extraño es que no se ven errores, simplemente no arranca.
