Unable to install new plymouth theme in Ubuntu, apart from the default ones

[austinrojers]

I tried to follow the following steps:

#make sure you have the packages for plymouth
sudo apt install plymouth

#after downloading or cloning themes, copy the selected theme in plymouth theme dir
sudo cp -r angular /usr/share/plymouth/themes/

#install the new theme (angular, in this case)
sudo update-alternatives --install /usr/share/plymouth/themes/default.plymouth default.plymouth /usr/share/plymouth/themes/angular/angular.plymouth 100

#select the theme to apply
sudo update-alternatives --config default.plymouth
(choose the number to the installed theme, angular in this case)

#update initramfs
sudo update-initramfs -u

It works with the preinstalled themes, But when I select a newly installed one, I just get my Dell logo until the login screen

Plymouth works during the reboot or shutdown process, but not on boot?

Could this be similar to this: https://forum.garudalinux.org/t/correct-plymouth-boot-theme-not-showing-up-on-boot/

If so, please tell me what the Ubuntu-specific steps are?

Thank you in advance

@adi1090x please have a look

it's probably because the default one tell Plymouth to drop the EFI framebuffer. try to add fbcon=nodefer to your kernel cmdline (when booting, press E when your are on the grub to edit your selected entry and add that to the end of the line starting by linux). It will tell the kernel to don't even keep that framebuffer so it will maybe let you see your theme

Thanks @Tutul, I no longer use Ubuntu or Ubuntu based distros. I will check it out, if I use Ubuntu in the future.
