I finally received my 3.5" KeDei 480x320 16bit/18bit version 3.0 TFT LCD touchscreen from Hong Kong. It only connects through the GPIO pins. I plugged it into my Raspberry Pi 2 and I was met with a white screen when I tried both the Ubuntu and Raspbian images.
I have updated Raspbian, I know that my good power supply is good, and I tried enabling the SPI kernel module through the Raspberry Pi Configuration GUI since the touchscreen says that it connects via SPI. The only thing that I think could be wrong now is that the drivers are not installed or that I don't have the right kernel.
If I can get the touchscreen to function on either the Ubuntu or the Raspbian image, then I will just take the one that works. Though if both could work flawlessly I think I would prefer using the Ubuntu image since I am more familiar with it.
