Le thème Plymouth nouvellement ajouté ne s'affiche pas pendant le démarrage

J'utilise Ubuntu 16.04 et quand j'ajoute et choisis un autre thème Plymouth autre que ceux ajoutés par défaut, lors du redémarrage pour tester, je le vois pendant le processus d'arrêt, mais lors du redémarrage, après grub, j'obtiens un écran noir avec rien sur jusqu'à ce que j'arrive à l'écran de connexion.

L'installation ne suffit pas

Chaque thème plymouth a une priorité et par défaut le plus prioritaire est choisi comme thème de démarrage. Vous pouvez le remplacer avec cette commande:

sudo update-alternatives -config default.plymouth

Qui montrent quelque chose comme ça:

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:

l'option actuellement sélectionnée (et par défaut) dans mon système est 0 (auto), vous pouvez le voir par le caractère astérisque (*).

Vous pouvez également voir quel est le thème sélectionné automatiquement.

Vous devriez voir votre thème y figurer, écrivez simplement le numéro dans la colonne Sélection et appuyez sur Entrée.

Ensuite, vous devez rendre votre modification effective, pour ce faire, exécutez cette commande:

sudo update-initramfs -u

Vous devriez voir votre nouveau thème au redémarrage.

Tout cela est déjà documenté à cette question.

J'ai eu le même problème (et bien d'autres) pour que le thème Earth-Sunrise de 2011 fonctionne sous Ubuntu 16.04.

Changer les noms de chemin du format <16.04 au format 16.04

Le fichier /usr/share/plymouth/themes/default.plymouthavait d'anciens chemins depuis Ubuntu 14.04 et devait être modifié pour refléter Ubuntu 16.04.

Assurez-vous que le vôtre contient des noms de chemin comme celui-ci:

[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

Tampon de trame dans initramfs-tools

Modifiez le fichier /etc/initramfs-tools/conf.d/splashet ajoutez cette ligne:

FRAMEBUFFER=y

Transition en douceur vers GDM

Pour permettre une transition en douceur, vous devez désactiver votre unité de gestionnaire d'affichage, par exemple

systemctl disable gdm.service

Activez l'unité DM-plymouth respective (unités GDM, LXDM, SLiM fournies), par exemple

systemctl enable gdm-plymouth.service

Activer le débogage

Modifiez le fichier /etc/default/grubet recherchez la ligne LINUX_DEFAULT:

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

et changez-le en ceci:

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

La note plymouth:debugest la chose importante. Il splashest également toujours nécessaire d'invoquer plymouth.

Après le redémarrage, regardez dans le fichier /var/log/plymouth-debug.loget il devrait ressembler à ceci:
