Specify which graphics adaptor GRUB should use
I have a motherboard with a simple 2D onboard graphics accelerator (I believe it sits on the PCIe bus). I have also installed a separate PCIe Nvida GeForce card which I would prefer to use exclusively. The onboard device only has a single VGA out - this is what GRUB defaults to using. I would like to not have to use the VGA interface at all. Is there a way to force GRUB to be displayed through the Nvidia adaptor?
This is particularly painful as I have to enter in the LUCKS HDD password over VGA rather than HDMI. Once booted Ubuntu will switch to the Nvidia adaptor.
Currently I am using two monitors - one connected to the VGA port, and one connected to the HDMI port on the Nvidia card. If I disconnect the VGA port, nothing changes, I just can't see the prompt for the LUKS password.

Does this mean you have two cables from your computer to the monitor: (1) VGA, (2) HDMI? If the VGA connector is not connected to the monitor, how does the onboard graphics control the display during the boot process? What happens if you disconnect the VGA cable? Please edit your question above and add the new information.
