Tema Plymouth recém-adicionado não aparece durante a inicialização

Estou executando o Ubuntu 16.04 e quando adiciono e escolho outro tema do Plymouth que não seja o padrão adicionado, ao reiniciar para testá-lo, vejo-o durante o processo de desligamento, mas ao inicializar novamente, após o grub, aparece uma tela preta sem nada até chegar à tela de login.

Instalá-lo não é suficiente

Cada tema plymouth tem uma prioridade e, por padrão, a prioridade mais alta é escolhida como tema de inicialização. Você pode substituí-lo por este comando:

sudo update-alternatives -config default.plymouth

Que mostram algo como isto:

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/ubuntu-logo/ubuntu-logo-scale-2.plymouth   99        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:

a opção atualmente selecionada (E a ​​padrão) no meu sistema é 0 (automático), você pode ver isso pelo caractere asterisco (*).

Você também pode ver qual é o tema selecionado automaticamente.

Você deve ver o seu tema listado lá, basta escrever o número na coluna Seleção e pressionar enter.

Então você precisa efetivar sua alteração, para fazer isso, execute este comando:

sudo update-initramfs -u

Você deverá ver seu novo tema ao reiniciar.

Tudo isso já está documentado nesta pergunta.

Eu tive o mesmo problema (e muito mais) de obter o tema terra-nascer do sol a partir de 2011 para funcionar no Ubuntu 16.04.

Alterar nomes de caminho do formato <16.04 para 16.04

O arquivo /usr/share/plymouth/themes/default.plymouthtinha caminhos antigos do Ubuntu 14.04 e teve que mudar para refletir o Ubuntu 16.04.

Verifique se o seu contém nomes de caminhos como este:

[Plymouth Theme]
Name=Earth Sunrise
Description=This theme is a modification of Andre "Osku" Schmidt's Space sunrise plymouth theme
ModuleName=script

[script]
ImageDir=/usr/share/plymouth/themes/earth-sunrise
ScriptFile=/usr/share/plymouth/themes/earth-sunrise/earth-sunrise.script

Buffer de quadros em initramfs-tools

Edite o arquivo /etc/initramfs-tools/conf.d/splashe adicione esta linha:

FRAMEBUFFER=y

Transição suave para GDM

Para permitir uma transição suave, você precisa desativar a unidade do gerenciador de exibição, por exemplo

systemctl disable gdm.service

Ative a respectiva unidade DM-plymouth (unidades GDM, LXDM, SLiM fornecidas), por exemplo

systemctl enable gdm-plymouth.service

Ativar depuração

Edite o arquivo /etc/default/grube procure a linha LINUX_DEFAULT:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vt.handoff=7 kaslr"

e mude para isso:

GRUB_CMDLINE_LINUX_DEFAULT="plymouth:debug splash vt.handoff=7 kaslr"

Nota plymouth:debugé a coisa importante. Também splashé sempre necessário para chamar plymouth.

Após a reinicialização, observe o arquivo /var/log/plymouth-debug.loge ele deve ser algo como isto:
