I have a old Dell laptop that I use as a media computer hooked to my TV. It was in rough shape when it was given to me as it has a broken keyboard and screen. I have been using it with my TV or my spare monitor and a wireless keyboard/mouse with windows 7.
When I go to install Ubuntu the external screen turns off right away. My guess is that it is defaulting to the OEM screen which has now been removed. I have tried FN F7 on my external keyboard to swap screens but I have had no luck. I have wiped Windows I would rather Ubuntu but I did not expect this.
I was thinking of trying a different Disro but I have Ubuntu on 3 other computers
