In a recent driver, Nvidia finally added Linux support for render offload, where most graphics are rendered on the CPU-onboard GPU and only certain applications are rendered on the discrete Nvidia GPU. I know that Ubuntu 19.10 started shipping some updated Xorg packages to support this. For the most part the mode seems to work great.
On my laptop, however, I have found that the "on demand" mode does not detect external monitors (and the monitor says it is not receiving a signal). Switching to "Nvidia" mode, where everything is rendered on the discrete GPU, makes the external displays work. The laptop is a Lenovo Thinkpad X1 Extreme (Gen 1). I have found this occurs both with nvidia-graphics-drivers-435 and nvidia-graphics-drivers-440 in the "graphics-drivers" ppa.
