dmesg, xorg, journal output (concatenated)

Despite support for GP108, it seems that I have problems with the mobile
variant, GP108M. While my system boots successfully with the kernel module
loading successfully (though with some warnings) my display manager cannot
start because no screens can be found by the Xorg server. I have attached logs
from dmesg, Xorg.log, and journalctl. I am on archlinux. Please let me know if
anymore information is required. I would *really* prefer to use the opensource
nouveau driver rather the closed nvidia...

--- Comment #4 from Pierre Moreau <pierre.morrow at free.fr> ---
Looking at the logs you provided, it's the NVIDIA kernel module that ends up
being loaded rather than Nouveau. And looking at the Xorg.log, you no longer
have the NVIDIA DDX so it’s the Nouveau one that is being loaded, but since it
can’t communicate with the Nouveau kernel module, it fails to find a device and
X exists because no screen was found.

I am assuming you removed the "nvidia-utils" package, but forgot to
remove the
"nvidia" one, which contains the kernel module.
