I'm running Ubuntu 20.04 and want to remove boot animation so then I can see the programs that are loaded into the system when it boots up.

What I want is to see the below screen. Not the Ubuntu logo.

  • The quiet splash setting in grub shows the logo. I found changing quiet splash to "noplymouth" also seems to speed up boot. Try once manually changing in grub menu with e and replace on linux line. If that works as expected then you can make permanent with edit to sudoedit /etc/default/grub and sudo update-grub

Reset to default

Edit /etc/default/grub and remove the string quiet splash from the line GRUB_CMDLINE_LINUX_DEFAULT=

Then run sudo update-grub.

Example for one of my pc's:

Before: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash stack_guard_gap=1"

After: GRUB_CMDLINE_LINUX_DEFAULT="stack_guard_gap=1"

    As far as I know, specifically, the quiet option suppresses the readouts that OP is after (but does not provide anything in place of it), while the splash is providing some kind of "user friendly" visual to at least show something while the system works on booting. That's how removing both leads to the desired result.

  • @Levente thanks! I learned something, I always thought "quiet splash" was one option!

Toggling to Traditional Text-based Boot

If you want to see the text-based boot messages (which use the Plymouth "details" plugin, press the ESCAPE key at any point when Plymouth is running. Note that the ESCAPE key acts as a toggle, so you can keep switching between graphical and text mode as required.

To show debug messages, you need to enter grub menu and remove quiet from options. You can permanently remove quiet from following line in /etc/default/grub, save and sudo grub-update

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet resume=UUID=YOUR_SWAP_UUID"

This way you won't have to remove the boot animation permanently

Permanently set to Traditional Text-based Boot

To have the boot start in "text mode" permanently, open /etc/default/grub as sudo and change the following line. Replace splash quiet with noplymouth, save file and run sudo grub-update

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet resume=UUID=YOUR_SWAP_UUID"

Of course run sudo update-grub every time you change this file /etc/default/grub.
