Problemas de resolucion de ubuntu

Archivado
Bueno tenia ubuntu 8.04 y al salir la version 8.10 decidi actualizar y lo instale formateando y haciendo una instalacion nueva y limpia, al instalarlo todo se queda bien, excepto la resolucion, solo deja poner 800x600 y 640x480, al instalar el driver privativo solo me deja poner 640x480 y 320xnosecuantos.
En los dos casos son resoluciones que no permiten utilizar ubuntu de forma comoda, tambien e probado a instalar los drivers desde synaptic y desde envy y el resultado es el mismo, si instalo el driver 800x600 y si lo habilito 640x480.
El driver de la pagina de nvidia al ir a instalarlo me dice que no soporta el kernel.
Otro intento fue desde Nvidia x server seting y intente forzarlo a utilizar 1280x1024 (que es lo maximo que admite mi monitor), el resultado es que la pantalla ocupa los 1280x1024 pixeles pero solo muestra 640x480 y segun muevas el raton se desplaza a una zona o otra.
Y por ultimo intente modificando el xorg.conf, por lo general las configuraciones que e puesto despues de googlear mucho solian joderme el archivo y al reiniciar tenia que volver al backup, el ultimo intento no me jodio el archivo, funciona pero como si no lo hubiera tocado.

Despues de mirar mucho por google y problemas similares por aqui ya no se me ocurre nada, al instalar los drivers privativos la grafica la reconoce (xfx nvidia 5700le), pero el monitor no (proview 780) y por eso no me deja aumentar la resolucion a mas de 800x600 en el mejor de los casos cuando mi monitor acepta hasta 1280x1024.
¿A alguien se le ocurre alguna solucion?
muestranos tu /etc/X11/xorg.conf, parece ser un problema con la SubSection "Display", pero es mejor asegurarse.
Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Defaultdepth 24
Modes "1280x1024""1024x768""800x600"
EndSubSection
EndSection

Section "Module"
Load "glx"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection

La parte seleccionada en negrita es la editada, el diver privativo de nvidia no esta activo.
Sin editarlo esa parte seria asi, Defaultdepth 24
Prueba con:
Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    Defaultdepth 24
    SubSection "Display"
        Viewport  0 0
        Depth     24
        Virtual   1280 1024
        Modes     "1280x1024" "1024x768"
    EndSubSection
EndSection


Lo del Viewport y Virtual deberia solucionarte el problema de desplazamiento de la pantalla con el cursor (y esperemos que la resolución tambien).
Nada que no, solo muestra 640x480 aunque el escritorio tenga 1280x1024 [mamaaaaa]
Sucede lo mismo con ambos controladores? (nv y nvidia).

Quiza en el /var/log/Xorg.0.log salga algo del porqué no te acepta la resolución .

En pocas palabras: el controlador de nvidia por X razon no pudo leer el EDID del monitor y pone una resolución por defecto.

Tengo tiempo que no uso una nvidia, asi que desconozco como usar la opción CustomEDID correctamente.

Prueba añadiendo la opcion de metamodes para forzar que use ese en ves del 640x480, si no funciona busca información de como usar la opcion del customEDID.

Te faltan los drivers del a grafica o al menos yo los he instalado y ya puedo poner una gama de resoluciones y no solo esas dos.
es el driver de nvidia se ve en la ultima linea te cambia a 1280 y despues a 640 ve que pasa desactivando el privativo
Bueno al final lo solucione volviendo a la version 8.04 y instalando el driver de nvidia desde envy.
Aqui pongo mi nuevo xorg.
No se si volviendo a 8.10 y poniendo este xorg funcionaria bien, pero de momento me voy a quedar con la 8.04.
gracias por la ayuda.

Buenas,tengo instalado ubuntu 8.10 y no me admitia resolucion 1024x768@60 siempre me arrancaba a 640x480 he probado de mil formas, mediante envy y modificando el xorg.conf y nada, hasta que he dado con tu configuracion de xorg,lo he probado y funciona con los efectos de escritorio 100x100, mi grafica es una nvidia fx5600xt, te animo a probar el 8.10, Saludos y Gracias.

Ok lo e vuelto a probar y ahora si va bien, no e necesitado modificar el xorg.conf que postee antes, instale el driver desde envy y a funcionar. XD
