What I think you are missing is that you are using Kali in VM. The drivers will not work in VM as they are being virtualized. This basically means that what your guest system "sees" is virtual hardware created by it, not your actual, physical hardware. So in essence any video drivers you try to install will not work as it doesn't really see the hardware but just a virtual representation of the hardware. As VM improves, perhaps that ability will be possible, but I don't believe it has yet. You would have to run Kali natively in order to use the drivers.
