Este es mi primer post, asi que saludos a todos los integrantes de este foro.
Os escribo para pedir ayuda. Hasta hoy estaba trabajando den LMDE2 y sin ningún tipo de problema.
(tengo un portátil un poco antiguo, es un intel core duo 2 a 64 bits). al bajar la live xfce de 64 bits de LM Tara y ejecutala, la resolución de la pantalla es la correcta, pero cuando la he instalado no pasa de 640x480.
He probado con el xrandr como se comenta en otro post y no he obtenido resultados:
