3,5" TFT only shows console

handlampe

Hi,

I'm trying to build my own Gameboy with RaspberryPi3 and RetorPiev4.1.
I'm using a Kuman 3.5" Display, see here: https://www.amazon.de/gp/product/B01FX7909Q/ref=oh_aui_detailpage_o01_s02?ie=UTF8&psc=1. It seems to be similar to the Waveshare 3.5" Display.
I've installed the latest drivers downloaded from the official site.
After this was able to see the console form beginning on, but I've never seen GUI (Xorg) on this display.
After this I followed the instructions on this site: http://futurice.com/blog/id-like-to-have-some-lcd-on-my-pi.
But I still can't see GUI. It seems the only thing that is missing is to redirect GUI to this display. But i thought this was an approach of fbtft (which is preinstalled on RetroPie4).
After this I tried to use fbcp like this:

sudo apt-get install cmake
git clone https://github.com/tasanakorn/rpi-fbcp
cd rpi-fbcp/
mkdir build
cd build/
cmake ..
make
sudo install fbcp /usr/local/bin/fbcp

With fbcp I can see the RetroPieMenu. But this can't be the solution. I guess it was about 1 to 2 Frames per Second. So fbcp is dismissed. :-D

I still think the only thing that is missing is a redirection of xorg to display. It seems the way the mentioned tutorial suggests does not work at all.

Here are some of my system files:

If something is missing let me know. Maybe its just some missing configuration. I hope some can help me with this.
Thanks in advance.
