As the title states. I know I can roll back to an earlier snapshot, but I'd like to fix it "the hard way" - cuz that's how you learn
Must be happening due to the latest (Nvidia) drivers being installed.
I've launched into tty, run inxi -G to check the driver version in use and pacman -Qs nvidia to check the driver packages installed - the numbers do not match. inxi says 455.23.04 is installed and also note: display driver n/a FAILED: nvidia, and pacman -Qs says mhwd-nvidia 455.23.04-1 and nvidia-dkms 455.28-1.
The "normal" initramfs contains only the stuff that you configured to be there (/etc/mkinitcpio.conf) and the "fallback" contains the default selection of drivers (eg all filesystem drivers, etc..).
