um .. provastes el estado de tu monitor ... asi como sus conecciones ?

[dlanor_1990]

monitor defectuoso al parecer pruevalo en otra pc

[DIALVIEN]

Gracias por su interes, les cuento que he probado el monitor y esta perfecto, antes de instalar ubuntu tenia xp y vista y no tenia este problema, probe colocandole una targeta de video pci y funciona perfecto, lo que pasa es que no puedo comprar la targeta grafica solo probe entonces no me queda sino buscar una solucion. creo que son los drivers de la placa base ustedes que opinan.

[VJEVans]

Um tienes razon puede ser los drivers o tbm puede ser que la conneccion VGA de la Mother ya este dañado ...

[juan_unreal]

checa que la salida de la mother no tenga ese problema, tambien suele ocurrir por las memorias ram que se dañan y te lo digo por que me ha pasado se empiezan a llenar de rayas la pantalla,

tambien es bueno revises los conectores ide o sata y que los discos duros esten en correcto funcionamiento

[DIALVIEN]

Te cuento que he probado con otra ram y lo mismo lo unico que no puedo descartar es la conexion, pero si se que en xp y vista funciono muy bien hasta hace una semana y el problema aparecio justa al instalar ubuntu 10.04 por lo que probe con el 10.10 y es lo mismo, no se si sea por lo viejita que es la placa hablo de poco mas de 4 años y tal vez no haya soporte, he buscado por la red un problema similar y nada. Seguire intentando, cualquier sugerencia bienvenida sea
gracias.
