Black screen at boot when i915.modeset=0 is not set
I have the following laptop (first model issued in January 2018)
Dell Latitude 5490
8th generation i7-8650U intel iGPU 620 (i915)
dGPU geforce MX130 (former 940MX) Maxwell architecture
500GB NVMe drive Toshiba
32GB RAM
I installed Arch from existing debian because Arch Installer crashes at some point.
After installation, I boot Arch and after a few line of messeges I get blank/black screen.
I found that 'nomodeset' or 'i915.modeset=0' allows to get login but I have problems with running Xorg (no screens found, xrandr - no devices found)
Since I have no logs during the boot with blank/black screen I took a picture just before (added 'debug' kernel parameter)
The last message line before getting blank screen is: "fb: switching to inteldrmfb from EFI VGA" (as seen in the picture)
Any help?

Kernel driver in use: nvmedmesg when using i915.modeset=0 is here:
So to summarize, if I understand it correctly, 'inteldrmfb' framebuffer leads to black screen (no response for Ctrl-Alt-F2), while with i915.modeset=0, VGA framebuffer is used and I can login but without possibility to run xorg.

Re: Black screen at boot when i915.modeset=0 is not set
jasonwryan, I don't see any solution in https://wiki.archlinux.org/index.php/NVIDIA_Optimus
I have no option to turn off Nvidia GPU in BIOS.

Re: Black screen at boot when i915.modeset=0 is not set
If you have dual cards, as far as I understand it, you have to set up your system with one of the nvidia-related solutions (optimus, bumblebee, whatever).

Re: Black screen at boot when i915.modeset=0 is not set
I thought that the problem is with kernel 4.14 or 4.15 not handling well my hardware. Without i915 modesetting, xrandr gives no output. Perhaps I should notify this problem as a bug in drm/i915 kernel core?

Re: Black screen at boot when i915.modeset=0 is not set
xrandr give you no output because it only runs in X.

Re: Black screen at boot when i915.modeset=0 is not set
If the nvidia GPU needs to be configured depends on a combination of if rafalsk wants to use that device and to which GPU the internal and any external screens are physically connected possibly configurable by firmware as well.
Without modesetting disabled does the system reach a console login without a blank screen? If not if you check the journal are there no records from a boot without modesetting disabled?
If you blacklist the nvidia module does that have any effect on the blank screen?

Re: Black screen at boot when i915.modeset=0 is not set
loqs,
1. Without modesetting disabled the system does not reach a console login. The result is that for a quater of second I see the screen with some messages which I took picture in my first post. Then the screen becomes black, I mean the there is black light on the screen but I can do nothing (Ctrl-Alt-F2 does not work). I cannot login even blindly to power off. Neither I have any records in the journal - simply as if the booting process is non-existing in logs. The final line before the screen goes black is "fb: switching to inteldrmfb from EFI VGA"
2. While with modesetting the journal log is in may post #2. I can login. From the journal (link in post #2) I see that EFI VGA frame buffer is used: "[ 5.722465] fb0: EFI VGA frame buffer device" instead of inteldrmfb. For now I see this difference which make to continue displaying boot messages.
3. I added nvidia module to /etc/modprobe.d/modprobe.conf blacklist. No positive results. 
Other than that I can say that the same situation is on debian installed on the same laptop. Both for debian and arch I have the same kernel 4.15. On kernel 4.14 both debian and archlinux (linux-lts) the difference is that the sole i915.modeset=0 is not enough to see the console login screen - instead I have to pass "nomodeset" to kernel parameters to get the login prompt.
EDIT:
here is the output of mkinitcpio -M
https://ptpb.pw/ENPp
EDIT 2:
My problem is similar to
https://bbs.archlinux.org/viewtopic.php?id=234659
but blacklisting nvidiafb does not help

Re: Black screen at boot when i915.modeset=0 is not set
I took another better picture of messages just before the screen becomes black and the system is blocked (with loglevel=7)

Re: Black screen at boot when i915.modeset=0 is not set
I checked that kernel 4.9 hangs at fb: switching to inteldrmfb from EFI VGA, but in this case the screen does not get black, I see all the messages. I need to press power button to reset.
Then I compiled kernel 4.4 and in this case without any nomodeset or i915.modeset=0 I get login prompt. I attach dmesg when kernel 4.4 is running. Note that in dmesg there is no line about switching to inteldrmfb from EFI VGA after which the hang (kernel 4.9) or black screen (kernel 4.14, 4.15) happens.
I filed a bug here:

@rafalsk I don't know if this will help you but you can try adding video=efifb to your kernel boot arguments.

m3thodic, thank you, but still I can see the same last line with inteldrmfb, and then the black screen.

Re: Black screen at boot when i915.modeset=0 is not set
Almost one month later there is a patch to fix this problem.
I applied the patch in the link below and now my computer boots properly.
https://bugs.freedesktop.org/show_bug.cgi?id=105549#c34
I can tell that rebuilding and applying this patch to archlinux kernel is easy, while in debian similar procedure is painful and following manuals I still get errors.
