xorg loggings with the problem

After upgrading my debian stable with a (i assumed) a nice cpu with graphics
AMD 2200G, it did not work, only in VESA mode.
I upgrade to unstable/sed and now have a non working system with default
settings.

For me it is not clear, where the problem is (kernel or amdgpu), but maybe you
can help me with steps to get it clear.

This are the warnings and errors:
[     9.874] (WW) AMDGPU(0): No outputs definitely connected, trying again...
[     9.874] (WW) AMDGPU(0): Unable to find connected outputs - setting
1024x768 initial framebuffer
[     9.874] (EE) AMDGPU(0): No modes.
[     9.874] (EE) Screen(s) found, but none have a usable configuration.

I have attached the following info:
* lshw -c video 
* dmesg 
* /var/log/Xorg.0.log 
* lsmod | grep amdgpu after boot.

I boot with kernel 4.16, to get a working VESA driver I use the "nomodeset"
flag on the kernel arguments.

What I also don't understand is why the system doesn't fallback on the VESA
driver?

Thanks already a lot!
