X fails to start after motherboard replace

Motherboard died (ASRock Z87 Pro3) died and I got a new one (ASrock Z97M Pro4). After getting Arch to boot again (had to re-do UEFI & GRUB), X won't start.

The Intel graphics drivers are loaded:

% sudo lsmod | grep i915

drm_kms_helper        106496  1 i915

Here's the pastebin of the full log file

I have 2 monitors, one connected to DVI and the other connected to HDMI. I have no /etc/X11/xorg.conf, and everything worked before the motherboard swap. I have experimented with installing the packages xf86-video-vesa and xf86-video-fbdev, but X still failed to start. I got more messages about the modes being reported by the monitors, but then X would segfault. Again, the end of the Xorg.0.log file:

Your system has 2 videocards, so you probably have a hybrid graphics setup.

Yes, I have an Intel Integrated GPU and a PCI nVidia card. I'm using the Intel GPU and blacklisting the nouveau & nvidia modules, and grabbing the nVidia card with pci-stub (for later VGA passthrough to a VM). Here's lspci -k as requested:

Re: X fails to start after motherboard replace

Well, we have found the problem then.

[  1912.219] (--) PCI: (0:0:2:0) 8086:0412:1849:0412 rev 6, Mem @ 0xef400000/4194304, 0xc0000000/268435456, I/O @ 0x0000f000/64
[  1912.219] (--) PCI:*(0:1:0:0) 10de:1380:3842:3759 rev 162, Mem @ 0xee000000/16777216, 0xd0000000/268435456, 0xe0000000/33554432, I/O @ 0x0000e000/128, BIOS @ 0x????????/524288

The 2nd line shows what linux/X see as your primary videocard, the one at 0:1:0:0 .
the first line shows your secondary videocard at 0:0:2:0 .
Now look for those addresses in lspci -k output, and you'll see that 0:1:0:0 is the nvidia card, while 0:0:2:0 is the intel card.

In short, your system tells linux the nvidia card is primary videocard and intel secondary.
X can only use the secondary card through the primary card which is blocked from X by pci-stub.

Try setting the intel as primary videocard in bios/uefi firmware .

Re: X fails to start after motherboard replace

Humm... thanks for the explanation. I understand it, and it makes sense. Except for the fact that I've already set the uefi firmware with the configuration that the IGD is primary. Looks like either a) I didn't do it right, or b) it's not listening. Either way, I've got a direction to go now.
