Considering Nvidia X Server Settings screenshot it seems there is a lack of PRIME Profiles item along those two items I see. Once I've met with this situation when I had Secure Boot enabled in my BIOS (UEFI). So my advice is try to find Secure Boot in your BIOS (UEFI) and disable it. After rebooting you should see PRIME Profiles where you can choose which video card should be active.

Here are some explanations on the subject: Why disabling “Secure Boot” is enforced policy when installing 3rd party modules

    Takkat edited the question, but did not ask it – Zanna Mar 27 '17 at 10:55
  • Zanna, I don't understand your comment. Do you consider my answer inappropriate for some reason? – Victor A. Mar 27 '17 at 14:24
  • Sorry, I was just pointing out that the person you are addressing only edited the question - it's not Takkat's screenshot. As to your answer itself, I am not sure; it seems more like speculation than a tested solution, but I don't have experience with nvidia issues. – Zanna Mar 27 '17 at 14:28
  • Oh, my fault about Tekkat :) – Victor A. Mar 27 '17 at 14:35
  • Turning `Secure Boot` really helped me. On my Desktop system with NVIDIA GeForce GTX 970 dedicated video card it made me able to see and use about 10 settings panes in the driver instead of 2 as the screenshot shows when `Secure Boot` was enabled. And on my notebook with Intel + NVIDIA GF750M by disabling `Secure Boot` it allowed me to see 3 instead of 2 driver settings panes - the third one is PRIME Profile which is required by the topic starter. – Victor A.
