Title: AMD/Nvidia switchable graphics not working Status in linux package in Ubuntu: Confirmed Bug description: 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.
