I' upgrading from my old HTPC (Xtreamer Ultra2) with a Geforce GT 520M graphics to a HTPC with an Athlon 200GE VEGA GPU.
I'm running the latest LE 9.2.2.
The HTPC is connected to an older AV receiver and from the receiver to an older FullHD TV via HDMI.
I had to solve two problems with my old HTPC:
1) the TV doesn't send a proper EDID, the EDID is missing 24Hz and 23.976Hz refresh rates
2) If the receiver was not on or it was switched to another input when powering on the HTPC, the HTPC started in some unsupported (by the TV) resolution (1024x768 I think)
I was able to solve both problems by this xorg.conf:

And I was so naive, that I thought that simply changing the driver from nvidia to amdgpu will work
It didn't ...
The problem probably is, that the amdgpu doesn't support the needed options.
Any ideas how to solve this with the new GPU
