I'm following the wiki https://wiki.archlinux.org/index.php/Silent_boot
I have enabled efistub boot and current my kernel parameter is : quiet loglevel=2 rd.systemd.show_status=false systemd.show_status=false rd.udev_log_priority=2 splash i915.fastboot=1 video=card-eDP-1:d
I have only intel gpu within cpu, no other external gpu.
The problem is there are 2 blanking screen in the boot process, once I think is in the bios switch bootloader, it quick flicker the vendor log. And then the screen brightness become low and when auto login in getty and startx, it quickly show the VT and became to my desktop finally.
So how could I continue debug and resolve this 2 flicker? I thought about using plymouth, but my computer boot very quickly and I don't think that can help something here.

The major problem here is I don't know why there is some junk frame in switch bios to booloader( I guess theme should be dropped from here), the screen first become black, then flicker vendor logo, finally retain the vendor log with low brightness than the bios showing.
I think the VT flicker may not be able to skip because I don't have a display manager and directly start x server.

I have a feeling this is a firmware issue. Perhaps go to your BIOS and see if there's a switch to disable vendor logo.
Do you also have i915 in your kernel modules?

Sure I have i915 module, and I have include it in initramfs modules
