AlmaLinux 9.4 with GUI: boot/reload messages

All situations in AlmaLinux 9.4 with
in the form of a rotating incomplete ring when loading GRUB2 and the kernel, as well as when it shuts down,
instead of the expected loading/shutdown messages:

These messages can be seen by pressing the down arrow symbol on your keyboard.
It is possible that you may not see the first messages.

I have not seen this in CentOS 7 and other Linux distributions.

If I’m reading you correctly, you have some system service which is not shutting down promptly. Many different services might have this problem. A picture would help, both to confirm my reading and identify the service or services.

No, on the contrary - it seems to me that this was originally invented (maybe described somewhere) by the developers - but I simply did not know about it. Although I have a server with a GUI installed on my PC at home, almost all server services are disabled as unnecessary.
I don’t mind having to press a keyboard key when booting.

Oh, you mean the “splash” but you want to see all the messages? What do you have in /proc/cmdline?

I didn’t even think about /proc/ !

It turns out quite strange: there
BOOT_IMAGE=(hd0,msdos1)/vmlinuz-5.14.0-427.22.1.el9_4.x86_64 root=UUID=53af7b93-7145-4723-9584-8f2d3fedb6f0 ro resume=UUID=c44cc38f-91ec-49a8-91bc-4e76 b121e6cd rhgb quiet crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M

But in /etc/default/grub
does not contain rhgb and quiet

  • and then in /boot/grub2/grub.cfg
    rhgb and quiet, of course, are also missing.
    And I see kernel messages after pressing the down arrow on the keyboard.
