[ubuntu] Questions about NVIDIA settings

I'm not sure where to put this; sorry if this is the wrong place

I have a MacBookPro5,3 with two GPUs: an NVIDIA GeForce 9400M and NVIDIA GeForce 9600M GT (only the 9600m is used), running Ubuntu 17.04 with proprietary NVIDIA drivers, and I have some questions about the nvidia drivers

1. I have a color profile but the Nvidia settings also has color correction settings and whenever I open the nvidia settings, or close a game, and elsewhere sometimes, my color settings are reset and I have to open the system settings and reselect my color profile. Is there a way to disable the nvidia settings from modifying the color configuration?
2. Is it possible to make use of the 9400M to achieve better performance? otherwise, is it possible to completely disable it? It might be the cause of glitches with fullscreen, and it reserves some of my ram for doing nothing!
These are my primary questions; I'll ask more later

some screenshots that might help:
