Thank you for your answer.
I do have two GPUs, the A6 and the RX550, and when the HDMI is connected to the A6, kodi starts correctly. If the HDMI is connected to the RX550, kodi does not start.

My debug logs: https://send.firefox.com/download/106e1d...AeG8NJ4l-w

Is it not possible to totally disable the A6 GPU in the BIOS? The kernel (and xorg) is seeing both GPUs, and is loading the radeon driver for the A6 GPU and the amdgpu driver for the RX550. The Xorg server seems to be crashing while initialising the RX550.

If you can't completely disable the A6 GPU then try blacklisting the radeon driver:

text:


echo "blacklist radeon" >/etc/modprobe.d/radeon.conf

and reboot.
