[Résolu] Crash au démarrage

Bonsoir,
Je viens d'installer ubuntu 1804 sur mon 2ème disque et lorsque je le lance (sur grub), l'ordinateur s'éteint après quelques secondes sur l'écran de démarrage. Lorsque que je fais un CRTL ALT F12 pendant le démarrage cela me donne ça : mini_200316085052555374.jpg
Avez vous une idée de la cause, sachant que le recovery mode fonctionne ?
Merci d'avance !

Re : [Résolu] Crash au démarrage

Bonsoir
Veux-tu dire par là, que tu peux booter en mode recovery puis choisir 'resume' et tout fonctionne?
J'ai vu  cela https://www.google.com/search?as_q=&as_ … as_rights= mais  le choix est vaste

Les grilles de l'installateur https://doc.ubuntu-fr.org/tutoriel/inst … _subiquity
"gedit admin:///etc/fstab" est proscrit,  utilisez "pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY xdg-open /etc/fstab" Voir  https://doc.ubuntu-fr.org/gedit

Re : [Résolu] Crash au démarrage

Exactement, je peux booter en recovery mode, puis resume et tout fonctionne normalement (sauf la résolution qui est pourrie). C'est juste en essayant de booter normalement que le problème arrive.

Re : [Résolu] Crash au démarrage

Bonjour
Il faudrait que tu regardes si ubuntu prévoit un pilote propriétaire.   Souvent, il faut d'abord faire une mise à jour logicielle

sudo apt  update
sudo apt  upgrade

avant que tu puisses le détecter dans la liste https://doc.ubuntu-fr.org/gestionnaire_ … prietaires

Re : [Résolu] Crash au démarrage

Bonjour,
Depuis une session démarrée en passant par le Recovery mode, je te prie de faire un Boot-info et de donner l'URL de ce Boot-info dans ta réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb4, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Advice in case of suggested repair
Veuillez désactiver SecureBoot dans le BIOS. Puis réessayez.Voulez-vous continuer ?


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !

Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


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

Peux-tu donner le nom complet du modèle de ton ordi et son fabricant ?

Re : [Résolu] Crash au démarrage

D'après le SSD de 256 Go et le disque dur de 1 To qu'on peut voir dans le Boot-info, je pense que le nom complet de ton modèle est GE72MVR 7RG-055FR qu'on peut voir sur cette page du site LDLC : https://www.ldlc.com/fiche/PB00229859.html
Ce modèle étant équipé d'une carte graphique dédiée NVIDIA GeForce GTX 1070, il convient d'installer le pilote propriétaire NVIDIA (mais peut-être que tu l'as déjà fait ?) et de désactiver Secure Boot. Cela reste à faire comme on peut voir dans cet extrait (il faudrait qu'on y trouve "SecureBoot disabled"): 

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this installed-session.
SecureBoot enabled.

Re : [Résolu] Crash au démarrage

Oui il s'agit bien de ce modèle. Après désactivation du secure boot, j'arrive enfin à accéder à ubuntu normalement et avec la résolution adaptée à mon écran !
Merci de votre aide !
Je mets le sujet en résolu
