Boots with fallback image, but black screen with normal image

While installing Arch to old 1st Gen Intel Core processor, I am getting blank screen (via ssh it works). But if I boot using fallback initramfs image Intel graphics works fine.

Question: How to determine, which module is missing in my initramfs? intel_agp and i915 are included.

Thank you in advance.

lsinitcpio command helps with that, check it's manpage.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Boots with fallback image, but black screen with normal image

As I understand it, the initramfs doesn't intrinsically need video modules, and adding them results in early KMS start (assuming KMS support). Compare the content of your images using lsinitcpio as Lone_Wolf suggested. But also:

* compare bootloader entries: are there any differences other than the initramfs image?
* compare dmesg, journal, and loaded modules after booting with standard to the same after booting with fallback
