I get the normal text lines from a verbose boot that just seems to stop… at that point, if I start typing the password, then the prompt will appear and asterisks for each character typed.
FWIW, I took quiet and splash out of /boot/firmware/cmdline.txt and added video=HDMI-A-2:1920x1200@60e.
I don’t think you need to rebuild the initramfs file when changing cmdline.txt, but just to be sure you could also do sudo update-initramfs -u before rebooting.
