20.04customizationplymouth
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.
Either the graphics drivers failed to load at boot, or nomodeset has been enabled, making the kernel not load the graphics card drivers. Check your boot settings.
UBUNTU 20.04
the live iso uses the file initrd which is inside casper directory.
this initrd file has the plymouth theme inside it, this is used for booting live iso. you can extract the contents and see what is being used for plymouth or any other config.
copy the initrd file to new directory.. and run
unmkinitramfs initrd .
So Editing the Plymouth contents as you wish and then recompile the new initrd file say myinitrd and use it to boot live iso instead of standard initrd file.
how to recompile the initrd to say myinitrd is a big task for me, I have offered two bounties in stackoverflow and unix & linux
Finally I got the answer from a smart person.. https://superuser.com/q/1556241/976939
the script is something like this..
#!/bin/bash
#mkdir 18
#unmkinitramfs initrd $HOME/18
# start with an empty file
touch $HOME/myinitrd
# Add the first microcode firmware
cd $HOME/18/early
find . -print0 | cpio --null --create --format=newc > $HOME/myinitrd
# Add the second microcode firmware
cd $HOME/18/early2
find kernel -print0 | cpio --null --create --format=newc >> $HOME/myinitrd
# Add the actual ram fs file system
cd $HOME/18/main
find . | cpio --create --format=newc | xz --format=lzma >> $HOME/myinitrd
# verify both initrds are the same
# binwalk $HOME/myinitrd
# binwalk $HOME/initrd
I confirm that using this method I have successfully customized the live iso Plymouth theme for the Ubuntu 20.04 ISO.

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