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.

Answer 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

Answer 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.

Answer 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

Answer 4

For anyone wondering why changing the watermark.png file inside /usr/share/plymouth/themes/spinner/ only changes the logo while shutting off but not while booting up, the reason is that while booting up, plymouth's bgrt theme uses the ubuntu-logo.png file located inside /usr/share/plymouth/
