Ubuntu with disk encryption doesn't show me encryption password dialog at startup due to i915

I am a "lucky" NVIDIA user with secure boot and TPM enabled. When I used Ubuntu without secure boot, TPM, and disk encryption (previous install), sometimes it worked well, sometimes it didn't, but every time I got it working without problems with NVIDIA.

Right now I need to edit GRUB and set i915.modeset=0, because without that I don't see the encryption password dialog.

What could be wrong? How can I fix this?

I have RTX 3070TI and 12th Gen Intel® Core™ i9-12900K × 24

Update: removing quiet splash and setting text instead for GRUB_DEFAULT_CMDLINE isn't working for me. Only modprobe.blacklist=i915 or i915.modeset=0

Is downloading this module necessary? Do I lose anything when I turn it off?

By this thread, then my problem would have remained unresolved, everything was fixed without any additional configuration, just when I inserted the hdmi wire into the motherboard connector, that is, the processor ...

If you, like me, have a graphics card built into the processor (iGPU) and two monitors that you connect to the connectors of your NVIDIA card, and for some reason you want the i915 module to be enabled, follow the following steps:

1. Remove i915.modeset=0 or everything related to disabling the i915 module from /etc/default/grub.
2. Run sudo update-grub to upgrade grub config.
3. Shutdown the PC.
4. Put the second monitor (in my case) to motherboard connector (instead of video card connector).
5. Reboot the PC.

If you don't have a second monitor that can make the i915 work and your system boot successfully, then probably the only way is to disable the module:

1. Just put i915.modeset=0 or nomodeset or modprobe.blacklist=i915 to your /etc/default/grub.
2. Then run sudo update-grub.
3. Reboot your PC

Update: Also if you don't disable i915 module disabling from /etc/default/grub I'll get unexpected behavior like random Wi-Fi module disabling (in my case) or
