Going through the "AtiHowTo" as suggested by IL Ka I made sure that all 
the packages are installed and I modified the xorg.conf as indicated there.

With "inxi -G" I get

Graphics:  Device-1: Advanced Micro Devices [AMD/ATI] Picasso driver: N/A
            Display: tty server: 1.20.4 driver: ati,radeon,vesa 
unloaded: fbdev,modesetting tty: 128x48
            Message: Advanced graphics data unavailable in console for root.

Xorg.0.log is now

Looking at the list of the drivers for the AMD/ATI Radeon chipsets I get 
a slight suspicion that the graphic chipset of the AMD Ryzen 5 3400G is 
not supported by Debia/Xorg as I don't find any driver for the Picasso
