So we'd want to get the provenance of that too. More a question to Christopher, but what criteria is preventing the use of the NVIDIA GPU under this condition? As far as I've seen on my (single-GPU) systems X requires the GPU to have boot_vga=1 sysfs attribute to accept autoconfiguration (though with two GPUs and optimus/switcheroo interaction between the GPUs may change the picture). I've been looking at the open, nouveau side of things only. If NVIDIA closed driver has some other requirement, I don't know. But as here the intention seems to be to use exclusively the NVIDIA GPU just leaving the IGD along it should require explicit X configuration which then does not care about boot_vga. A more detailed description of what prevents operation with GPU not being added to vgaarb would certainly help understanding what happens, what is expected and where things differ.
