Thank you for your replies.
After many additional tries (reinstall xserver-xorg-video-amdgpu,
running with and without xorg.conf) I think the problem is again (I have
found several references to this problem in other environments)
indicated by the message
[ 7.655] (EE) open /dev/dri/card0: No such file or directory
How do get (where do I find) "/dev/dri/card0" ??

In most cases there is no need to run "-configure" since X can
autodetect many things using defaults provided by distro.
Have you tried official debian wiki (it is about amdgpu, not general
modesetting)
https://wiki.debian.org/AtiHowTo ?
I think that "/dev/dri/card0: No such file or directory" means there is
no kernel driver (no module compiled or not loaded by udev)
Do you run custom kernel? Have you tried to load module manually using
(modprobe)?

Hello,
I installed Debian on a PC with AMD Ryzen 5 3400 G.
My first trials ended with a message
"Cannot run in framebuffer mode ..." from xorg.
Due to some research in the net I am using the following xorg.conf.
It is basically what I got when I did a "X -configure".

Somewhere I found the hint that the driver for framebuffers is
"modeseting"
Thus I changed in the Device sections for Card0/Card1 the driver to
"modesetting"
Now the startup of X ends as follows:

====
What I find strange is that the log says there is no device
/dev/dri/card0
while X -configure inserte thesi section into the conf-file.
Does anyone have a solution for this problem?
Thanks in advance
