How to switch console from integrated graphics card to NVidia?

Question

linux

Linux sentry 4.9.51-calculate #1 SMP PREEMPT Fri Oct 20 12:17:54 +07 2017 x86_64 Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz GenuineIntel GNU/Linux

By the will of providence, I had to use a commercial driver from NVidia. Latest version from portage, 384.90, map:

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108 [GeForce GT 730] [10de:0f02] (rev a1)

ASUS Prime Z270-P mother, it also has an integration with DVI and HDMI connectors.
And here is a strange thing that happens. Firewood from NVidia is loaded, everything is fine, but at the moment when the console should show the log of loading and starting services (splash=off in the kernel startup parameters) - it does not show anything - just a blank screen with the lines "Loading a list of commands Loading linux 4.9. -51-calculate Loading initial ramdisk" - and so on until the DM is loaded. After loading the DM, if you press Ctrl-Alt-F1 - we will see the same inscription again - there is no console! But it is not there because it is displayed on the integral (if you pick up a monitor there - here it is!).
The question actually is - how to make the console displayed on NVidia, and not on the integration - do not cling a separate monitor there?
Nouveau cannot be used - it does not support this card.

Answer 1

Well, in general, torsion-spinning of various ways to disable the integration does not work. It cannot be disabled in the BIOS, I did not find ways to disable it without rebuilding the kernel (to bring out support for intel). Replaced nivdia with an older one:
nouveau has earned, two monitors in DVI and HDMI - and happiness has come. Well, relative :)
