I have installed a nVidia Geforce 780 card on my desktop. My motherboard has a onboard display port too. My Bios has the following choices of display

• Auto, CPU Graphics, PCIe, PCIx.
• Multiple Monitors Enabled/Disable

When I choose CPU Graphics and Disable the Multiple Monitors setting in the BIOS, the desktop boots using the Onboard graphics port. But as soon as ubuntu X loads it switches to the Nvidia card. How do I fix this ?

I tried using nvidia-settings from this answer, but that has only choice of Monitors. All other posts talk about BIOS settings, but I think its a X issue and not a BIOS issue anymore.

Fixed it, I followed the steps on this video. Basically Additional Drivers, select the latest Nvidia driver and hit Apply. Open Nvidia XServer Settings and choose PRIME profiles, select Intel graphics card. Fixed.
