Hi there,
Thanks a lot for your comments.
The display I am trying to set up is a 17" TFT screen. I have been
trying both the DVI direct connection and the DVI/VGA adapter with no
success at all. In fact, the display shows some sort of scrambled
dessign where some parts of the Gnome desktop can be recognized (for
example, a moving icon on the top bar). In fact, this problem is not
restricted to de X's as I am also unable to see the console on the
external display. Any other ideas?
