--- Comment #3 from Marcin Zajaczkowski <mszpak at wp.pl> ---
I managed to build 5.2.0-0.rc3.git2.1.fc30.x86_64 on Fedora 30 and boot with
overridden NvChipset (0x167). The nouveau module is loaded, the card is visible
by vgaswitcheroo, but I cannot switch to it (nor force to turn it on).

there is no effect. On:

I see an error in the system logs:
> kernel: vga_switcheroo: client 0 refused switch

The initialization logs on boot:

There are also no reported providers in xrandr:

I don't know if it is related to the chipset itself or to my laptop
configuration. The same situation is with with 0x167 and 0x162.
