Hi,
I have two different types of GPU on my machine, GeForce GT 710 and GeForce RTX 2080 Ti. I want to use GeForce GT 710 for display and GeForce RTX 2080 Ti for training models only.
In my OS config, I have
videoDrivers = [ "nvidia" ];
but I don’t think the driver is working well on GeForce GT 710, because its HDMI and DVI ports are not detected, though the card itself is detected.
My question is:
Is it possible to specify in the OS config which card uses which driver? How?
