Public bug reported:
On a system with AMD Ryzen 5 and Nvidia GTX 1650 switchable graphics are
not working.
Just to get the drivers working for the respective chipsets, I had to
upgrade to kernel 5.6 for amd and install nvidia 450 drivers for nvidia.
This gets us to the point where both cards are operational. However, I
have to manually in xorg scripts essentially use my nvidia card as
primary because otherwise it just wont be used.
