10de:1c8c [MSI] nouveau fails to manage GP107M [GeForce GTX 1050 Ti Mobile]

I am trying to use my Nvidia GP107M [GeForce GTX 1050 Ti Mobile] with Linux kernels from Ubuntu 17.10 (Artful) and http://kernel.ubuntu.com/~kernel-ppa/mainline

At this day, when I issue 'lspci', the only 'nouveau' module of the kernel which succeeds comes from Linux kernel Linux kernel 4.14.0-041400rc7 from http://kernel.ubuntu.com/~kernel-ppa/mainline

Even with this Linux kernel 4.14.0-041400rc7, Xorg systematically crashes as soon as I try to really use Nvidia GP107M [GeForce GTX 1050 Ti Mobile] with the attached '20-onboard-monitor-nvidia-nouveau.conf' file :
