hello I have a sony vaio laptop with a core i5,
because the main screen is completely damaged, I have removed it ...
I have managed to install ubuntu 20.04 LTS and with the function key + f7 I have managed to see the main screen of Ubuntu to make the necessary configurations and set the secondary monitor as the main one.
already verified that the equipment works correctly I have installed in a USB Batocera, so that the children can use this equipment for game by emulator; the first boot was fine, I could see the autoconfiguration of the operating system on the secondary monitor; but after a few minutes the screen went black and lost the signal from the laptop; I know that it turns on correctly because it has sound and it is heard in the background but not more than that ... is there any way to make this thing work without having to buy a new screen for the laptop ???
