[ubuntu-ar] Monitor P2370ms y Nvidia fx 5500

[Santiago Paleka]

Hola grupo, acabo de instalar ubuntu 10.04 en una mother asus con
micro athlon 2800+ y una placa de video agp nvidia fx5500, estoy
usando un monitor samsung p2370ms con conexión dvi.
El problema es el siguiente, la instalación anduvo perfecta, con la
resolución en 1920x1080 que es la máxima del monitor.
En cuanto instalo los drivers privativos de nvidia, la resolución
máxima que me permite es de unos asquerosos 1600x1200.
No se que poner en el xorg.conf, cada vez que lo toco no me arrancan
las x. el xorg actual es:
