I’ve installed LM19 to my Dell and the inxi -Fxz gave similar reading of having two graphic card entries. Intel 530 and the ATI card. There is no proprietary drivers on offer for my ATI card.
Whereas my new rig with the 1060 Nividia card only has the one line. As you can see from the second picture and Nvidia settings.
Out of curiosity what does your Driver Manager and Nvidia settings tell you.
