Since you're running an rpmfusion build of myth I wonder why you don't 
use their nVidia packages.  I have the fc28 version of this with a 
GT710, and don't remember having taken any special measures.

xorg-x11-drv-nvidia-415.27-1.fc29

But I believe fc29 uses Wayland graphics by default; that may have 
changed things.
