How to change the logo shown during booting in Ubuntu?

How to change the logo shown during booting in Ubuntu? I originally installed Ubuntu MATE 18.04. But I am using GNOME 3 now by replacing the DE. But the log shown during booting is still Ubuntu MATE’s. How to change it to another one?

It is plymouth the application that manages the “splash” screen during booting and shutting down an Ubuntu system.

You can configure and choose which theme plymouth uses.

First, find all available themes by

sudo apt list plymouth-theme*

It will show available ones like

plymouth-theme-breeze/bionic 5.12.4-0ubuntu1 amd64
plymouth-theme-edubuntu/bionic,bionic 15.12.1 all
plymouth-theme-hamara/bionic,bionic 1.0 all
plymouth-theme-kubuntu-logo/bionic,bionic 1:18.04ubuntu11 all
plymouth-theme-kubuntu-text/bionic,bionic 1:18.04ubuntu11 all
plymouth-theme-lubuntu-logo/bionic,bionic 0.71 all
plymouth-theme-lubuntu-next-logo/bionic,bionic 0.71 all
plymouth-theme-lubuntu-next-text/bionic,bionic 0.71 all
plymouth-theme-lubuntu-text/bionic,bionic 0.71 all
plymouth-theme-sabily/bionic,bionic 1.3 all
plymouth-theme-sabily-text/bionic,bionic 1.3 all

plymouth-theme-ubuntu-budgie-text/bionic,bionic 0.9.6 all
plymouth-theme-ubuntu-gnome-logo/bionic-updates,bionic-updates 18.04.0 all
plymouth-theme-ubuntu-gnome-text/bionic-updates,bionic-updates 18.04.0 all
plymouth-theme-ubuntu-logo/bionic,now 0.9.3-1ubuntu7 amd64 [installed]
plymouth-theme-ubuntu-mate-logo/bionic,bionic,now 18.04.11 all [residual-config]
plymouth-theme-ubuntu-mate-text/bionic,bionic,now 18.04.11 all [residual-config]
plymouth-theme-ubuntu-text/bionic,now 0.9.3-1ubuntu7 amd64 [installed]
plymouth-theme-ubuntustudio/bionic,bionic 0.54 all
plymouth-theme-xubuntu-logo/bionic,bionic 18.04.5 all
plymouth-theme-xubuntu-text/bionic,bionic 18.04.5 all
plymouth-themes/bionic,now 0.9.3-1ubuntu7 amd64 [installed]

Second, install those you would like to use, such as plymouth-theme-ubuntu-text and plymouth-theme-ubuntu-log, by.

sudo apt install plymouth-theme-ubuntu-text plymouth-theme-ubuntu-logo

Third, choose the default plymouth theme used:

sudo update-alternatives --config default.plymouth

It will show choices to let you choose:

There are 2 choices for the alternative default.plymouth (providing /usr/share/plymouth/themes/default.plymouth).

  Selection    Path                                                         Priority   Status
------------------------------------------------------------
* 0            /usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.plymouth   100       auto mode
  1            /usr/share/plymouth/themes/spinner/spinner.plymouth           70        manual mode
  2            /usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.plymouth   100       manual mode

Press <enter> to keep the current choice[*], or type selection number: 2

Last, update the initramfs by

sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.15.0-29-generic

.

Then next time you boot the Ubuntu box, it will use the new splash theme.
