Well in that case it seems that you don't have the Optimus technology even though you have 2 GPUs. I have no experience on how to enable that Intel GPU apart from taking the Nvidia card out. There certainly is an option with tinkering the X server parameters, but since I don't have a test case to test it, I cannot recommend an exact solution. So maybe indeed try to remove the Nvidia card or maybe someone more experienced would know how to switch to the Intel GPU.
Now that I think more about it, at the beginning when you detected that you have 2 GPUs and both were being used, the reason for this was that you don't have Optimus, but have 2 GPUs and the system thinks both are used. That also can be the reason for the crashes.
