You can plainly see I was wrong, nouveau works fine with Nvidia seeing as how I've not installed the drivers yet!
So yes, while nouveau does work with my Nvidia GTX 980M, it pales in comparison to actually using the latest Nvidia driver. (384.90) Colors seem deeper, DPI is seriously affected and changed when comparing between Nouveau and Nvidia drivers.

Another reason I've switched back to using Nvidia, is that with the Nouveau driver, after a couple of hours of inactivity, black screen and nothing to do but reboot to get it back. Yes I know, I have a custom Kernel, but have never ran into this with Nouveau before. I do know that the 980M had issues with Nouveau in the beginning.
Anyway, we'll see if the black screen issue is fixed simply installing the Nvidia driver. Let you know next month!
