Ramdisk boot messages do not display correctly when boot messages are enabled. Ubuntu 20.04.3

I edited /etc/default/grub and changed the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

GRUB_CMDLINE_LINUX_DEFAULT=""

Then ran sudo update-grub and rebooted.

Ramdisk messages display like this during boot:

But the boot messages display correctly:

If I go into "recovery mode", Ramdisk boot messages display correctly. Is there a setting I am missing? I did not have this problem when I was running Ubuntu 18.04.6.

As requested, Here is my CPU info:

inxi -C

CPU:
  Topology: Dual Core model: Intel Celeron N3050 bits: 64 type: MCP 
  L2 cache: 1024 KiB 
  Speed: 547 MHz min/max: 480/2160 MHz Core speeds (MHz): 1: 538 2: 480

Does your notebook use an Intel or AMD graphics adapter at boot?

@matigo I am going into "uncharted territory" here. What command should I use to find that out?

Do you have multiple graphics devices in your notebook? If you're using an Intel chip with onboard graphics, chances are you are using the built-in graphics. If it's an AMD processor, then you're likely – though not guaranteed – that you're using the dedicated graphics device

@matigo Can you answer my previous question to your comment before we move on? If not, My notebook is a Acer Aspire One, model AO1-431. It of course has a built in graphics display, but also has a builtin HDMI interface, which I leave disconnected at boot time. There are no other graphic devices. Furthermore, there have been no hardware changes since my upgrade from Ubuntu 18.04.6 - I have updated my question with requested information. Thank you for your inquires!

[Based on the spec list from Acer](https://www.acer.com/ac/en/CA/content/model/NX.SHGAA.004), your system has integrated graphics. That means that if you are following the answer below, you would add `i915` to the `modules` file

You will likely need to add the name of your video driver module to /etc/initramfs-tools/modules:

  1. Edit /etc/initramfs-tools/modules with sudo:

    sudo {editor of choice} /etc/initramfs-tools/modules

    Note: Be sure to replace {editor of choice} with your editor of choice.

  2. Add the name of your video driver module to the end of the file. Here is a short list outlining the most common values:

    Name Graphics Adapter
    amdgpu for modern AMD-based systems (use radeon if you have something from before 2010 or need the legacy ATI driver)
    i915 for Intel graphics
    nouveau for the open-source Nouveau driver
    mgag200 for the old-school Matrox graphics
    nvidia nvidia_modeset nvidia_uvm nvidia_drm for Nvidia ... because why have one option when you can have four?

  3. Save the file and exit

  4. Update initramfs:

    sudo update-initramfs -u

  5. Reboot

This will give you everything you need.

Note for people using full disk encryption:

If you've also removed quiet from GRUB_CMDLINE_LINUX_DEFAULT, you will have a very 90's era experience when unlocking the volume. The nice password screen is replaced with a simple text-based "Enter password" after some of the preliminary boot messages are displayed.

+1 for your answer. Just for the record, I am not using encryption. Your answer provided a partial solution to the problem. ramdisk boot messages still start with hieroglyphic messages then switch to human readable messages. I am still confused to why a OS upgrade (without a hardware change) would necessitate a configuration change to `/etc/initramfs-tools/modules` Nonetheless, your solution is acceptable and safe for a live system. (I do not run VM, one mistake would destroy my system)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
