Boot working but its output only show two lines

On my Arch Linux-based distro with GNOME 44 and linux-zen kernel, baremetal installation and UEFI, after the installation of the system, I noted that, during the boot process, only two lines are showed:

Loading linux linux-zen ...
Loading initial ramdisk ...

then, it stays frozen for 15-20 seconds (during these seconds it flashes for 1 second to show also the grub background) and then jumps directly on the Display Manager (GDM) with no output shown.

Furthermore, when I reboot or power off the system, for 1 second it shows the grub background with the two lines "Loading linux linux-zen ..." and "Loading initial ramdisk ..." as it was a "flash" of the initial boot.

If I use VMware or Virtualbox, I dont still get the output but at least I don't get that "flash" of the grub background when I power off.

The "/etc/default/grub" file content is the following:

# GRUB boot loader configuration

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Athena OS"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3 audit=0 nvme_load=yes zswap.enabled=0 nowatchdog"
GRUB_CMDLINE_LINUX=""

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"

# Uncomment to enable booting from LUKS encrypted devices
#GRUB_ENABLE_CRYPTODISK=y

# Set to 'countdown' or 'hidden' to change timeout behavior,
# press ESC key to display menu.
#GRUB_TIMEOUT_STYLE=menu

# Uncomment to use basic console

#GRUB_TERMINAL_OUTPUT=console

# The resolution used on graphical terminal

# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1280x720

# Uncomment to allow the kernel use the same resolution used by grub
GRUB_GFXPAYLOAD_LINUX=keep

# Uncomment if you want GRUB to pass to the Linux kernel the old parameter
# format "root=/dev/xxx" instead of "root=/dev/disk/by-uuid/xxx"
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_RECOVERY=true

# Uncomment and set to the desired menu colors.  Used by normal and wallpaper
# modes only.  Entries specified as foreground/background.
#GRUB_COLOR_NORMAL="light-blue/black"
#GRUB_COLOR_HIGHLIGHT="light-cyan/blue"

# Uncomment one of them for the gfx desired, a image background or a gfxtheme
GRUB_BACKGROUND="/usr/share/backgrounds/default/grub.png"
GRUB_THEME="/boot/grub/themes/athena-logo/theme.txt"

# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"

# Uncomment to make GRUB remember the last selection. This requires
# setting 'GRUB_DEFAULT=saved' above. Change 0 into saved.
# Do not forget to 'update-grub' in a terminal to apply the new settings
#GRUB_SAVEDEFAULT="true"

# Uncomment to make grub stop using submenus
#GRUB_DISABLE_SUBMENU=y

# Check for other operating systems
GRUB_DISABLE_OS_PROBER=false

Why do I get this flash and I don't get any output during the boot process? Is it normal?

Re: Boot working but its output only show two lines

Are we talking Arch Linux or "Athena OS"?

Athena is pretty Arch 100%, with just GNOME extensions. I just tested also on Arch Linux (latest version 2023.05.03) with GNOME as DE in baremetal and I get the same effect. For checking the "flash" I explained above, try to assign a background image to grub.
