>> 2.- Si ves algo en la pantalla como oscuro o lo que llamamos "fondo de

>> eletrónico) larga como del tamaño de un marcador/boligrafo que va en la
>> parte baja de monitor.
>>
>> 3.- Si ves algo al iniciar y luego al entrar al GRUB no ves nada debe ser
>> un problema de software (drivers), alguna incompatibilidad o daño en el S.O.
>>
>> Pruebas:
>>
>> 1.- Iniciar con un monitor externo.
>> 2.- Iniciar con monitor externo con un Live/CD de alguna distro que maneje
>> buena cantidad de drivers.

>> De alli es un buen principio para detectar la falla, saludos.
