Ecran noir au démarrage Ubuntu 16.04

Bonjour,

j'ai installé la semaine dernière Ubuntu 16.04 sur mon Dell Inspiron N5110 (config d'origine sur Windows 7).

Quand je démarre, un écran noir s'affiche sans passer par l'écran de chargement d'Ubuntu et j'attends ... mon ordi ne démarre jamais.
Il finit par démarrer au bout de plusieurs essais et ce soir, j'ai pu faire un Boot-Info dont voici le lien :
http://paste.ubuntu.com/25222901/

Merci pour votre aide,
Maximilien

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda, using the following options:        sda1/boot,
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (500GB) !


=================== User settings
The settings chosen by the user will not act on the boot.

On y voit que tu as installé la version avec hwe stacks de Ubuntu 16.04 parce que tu as un noyau de la famille 4.10.0-x comme on peut voir (entre autre) sur cette ligne :

BOOT_IMAGE=/vmlinuz-4.10.0-28-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=7

Cela ne convient pas à ton ordi qui est une antiquité : c'est la version sans HWE stacks de Ubuntu 16.04 qui lui convient (explications ici mais tu n'es pas obligé de lire ni de comprendre ce que ça raconte. Par contre, ce serait utile que tu comprennes ce graphique qui me parait explicite). Pour ce faire, il faut réaliser une LiveUSB Ubuntu 16.04.1 64 bits à partir du fichier ISO "ubuntu-16.04.1-desktop-amd64.iso" téléchargeable à cette adresse : http://old-releases.ubuntu.com/releases … -amd64.iso
Pour le faire depuis une session Windows, je te conseille ma recette en béton armé : https://forum.ubuntu-fr.org/viewtopic.p … #p21556450
Pour la réaliser par un autre moyen, il y a la doc généraliste Live USB

EDIT : si tu choisis "Effacer le disque et installer Ubuntu" pour l'installation , je te prie de ne pas cocher la case "Chiffrer la nouvelle installation de Ubuntu par sécurité" ni la case "Utiliser LVM pour la nouvelle installation". Ce sont des nids à emmerdes, surtout le chiffrage de l'installation.

Salut Malbo,

je te remercie pour ta réponse.
J'ai fait hier soir la manipulation que tu as décrite, ça a l'air de fonctionner après plusieurs reboot big_smile

Merci pour ton aide,

Re : Ecran noir au démarrage Ubuntu 16.04

Bonjour,
Il y a une ligne pour le modèle "Inspiron 5110 N" dans la Liste des portables « Dell ». j'ai l'intention de rectifier le nom du modèle en "Inspiron N5110" et de mentionner ton expérience dans cette ligne. Pour donner un exemple d'install de 16.04 réussie dans ce modèle, je te prie de faire un Boot-Info depuis une session de ton Ubuntu installé et de donner l'URL de ce Boot-Info dans ta réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 16.04.1 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


=================== User settings
The settings chosen by the user will not act on the boot.

Tout me semble parfait là-dedans.
EDIT : je viens de mentionner ton cas dans la ligne du modèle "Inspiron N5110" de la Liste des portables « Dell »

Re : Ecran noir au démarrage Ubuntu 16.04

Bonjour,
Pour ma part j'ai pu installer Ubuntu 16.04.3 64 bits en dual boot avec Windows 7 sans problème sur mon Dell Inspiron N5110 datant de fin 2012 (OS d'origine: Windows 7, processeur Intel i5, carte graphique ATI Radeon HD 7450M couplée avec la carte intégrée Intel HD graphics 3000).
Je dis bien la 16.04.3 et non la 16.04.1.
Seul problème rencontré: juste après l'install à partir de la session live (qui tournait nickel), ça redémarrait directement sur Windows 7 sans passer par Grub (problème d'EFI ?!). La résolution du pb a été une simple formalité : j'ai fait le boot repair (simple copier-coller de ligne de commande dans le terminal, très bien expliqué sur le site) - "options recommandées" comme indiqué sur le site, et voilà, Grub fait bien son boulot, tout est fonctionnel!
Pour preuve mon boot-info est ici:
http://paste.ubuntu.com/26381429/
Voilà, désolé d'être un peu long, mais je tenais à signaler mon expérience positive car en lisant les posts ci-dessus, j'ai failli renoncer à installer la 16.04.3 LTS sur mon Dell, alors que ça a très bien marché sur ma conf! Ce qui est génial avec la session live, c'est qu'on peut tester une version sans installer, avec Firefox ouvert pendant l'install. Super smile Aucun problème de carte graphique non plus (ça souffle normalement!).
Merci
