--- Comment #3 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Kernel 4.4 did not have any acceleration support for GM20x, that support was
added in Kernel 4.6, in the presence of the nvidia-supplied firmware.

Nothing in your original logs seems wrong to me. Perhaps you never configured
offloading properly? (Sometimes the desktop manager will do it for you, depends
on ... the desktop manager, version, and, I'm sure, its configuration.)

See https://nouveau.freedesktop.org/wiki/Optimus/ specifically the bit about
"using outputs on discrete gpu".
