hi, i found where the problem comes from, i wanted to install the linux-tkg kernel to see if there was a difference. if we have " broken " packets, dpkg can't run correctly. so we have to install amdgpu manually from a terminal (or from the recovery option)
after that everything went back to normal with the gpu acceleration working perfectly and the drivers too.
