I have a Raspberry Pi 2 Model B and I bought an 3.5" LCD screen from China called Kedai 3.5. To be able to use it, the Chinese company provides a link for downloading a Raspbian image with the screen driver installed. After loading this image to the SD card, the Raspberry Pi boots up perfectly.
But: As I don't trust their image to be free of any spyware or virus, I would like to transfer the necessary drivers from that working Raspbian system and download and install Ubuntu 16.04 from here.
I already tried to copy the
*.img files from
/boot/ and as well to copy all the files in
/lib/ from the working Raspbian to the desired Ubuntu. Unfortunately, without success. After having done so and trying to boot the system on the Raspberry, the screen remains white.
What files and folders do I have to transfer to make that work?
