Ubuntu 20.04 boot logo image directoy

Question

I would like to change this default ubuntu logo

But I can't find it. I tried to change

/usr/share/plymouth/ubuntu-logo.png

But that is the image on the login screen. Can you tell me how to change it or where is this file located?

update: I changed that image and it actually works.

Solution 1

A basic search results that the ImageDir is /usr/share/plymouth/themes/spinner

[Plymouth Theme]
Name=BGRT
Description=Jimmac's spinner theme using the ACPI BGRT graphics as background
ModuleName=two-step

[two-step]
Font=Ubuntu 12
TitleFont=Ubuntu Light 30
ImageDir=/usr/share/plymouth/themes/spinner

It is not good idea to replace lot of Images of this spinner..

Instead find out a simple Plymouth theme which uses single Image and replace it..

If you want to change Ubuntu logo..

this is the Image file

/usr/share/plymouth/themes/spinner/watermark.png

Solution 2

All plymouth data and config needs to be embedded inside initramfs to be applied in iso boot, so you need to apply:

update-initramfs -u

Try this and check the results.

Solution 3

I needed to change 2 files:

/usr/share/plymouth/ubuntu-logo.png
/usr/share/plymouth/themes/spinner/watermark.png

And then update the initramfs as has been mentioned before:

update-initramfs -u

Sorry, I changed that image and it actually works, but using Cubic to create a new ISO the image of the ubuntu logo continues to appear before the installation phase, while actually after the installation it vanishes for the "new" image. Could you please help me?
