[RESOLU] ouverture session bloquée en boucle

Bonjour,

Je me permets d'ouvrir une nouvelle session car je viens de recevoir mon nouvel ordinateur : asus gl502vs.

L’ordinateur a été livré avec windows 10 et je viens d'installer Ubuntu 16.04.1 LTS  en dual boot sans souci. Cepdenant l'interface graphique n'était pas bonne (resolution, etc ...) j'ai donc installer le pilote pour ma carte graphique Nvidia et lors du redémarrage impossible de passer l'authentification qui tourne en boucle.
Le mot de passe est bon, ça charge, une page noir apparait pdt 1/2 seconde "/dev/sda5: clean, 190976/938400 files, 1170422/3749888 blocks" et ça revient sur l'interface graphique pour rentrer le mot de passe.

J'ai essayé les solutions de base sans succès:

sudo startx

et

sudo rm -fi .*authority*
sudo rm -fi .xsession-errors*
sudo reboot

En espérant avoir été clair (je suis débutant sur linux/ubuntu. En vous remerciant par avance.

Cordialement,

Re : [RESOLU] ouverture session bloquée en boucle

Je pense qu'il faut "désactiver Secure Boot". Si ça résout le pb, je te prie de le confirmer dans ta réponse parce que je ne suis pas du tout certain que ce soit le bon remède.

EDIT : à ma connaissance, la commande "sudo startx" n'a JAMAIS fait partie des solutions de base. Au contraire, cette commande provoque le problème d'ouverture de session en boucle comme je l'explique dans ce post (c'est dans la partie "Ce qui suit est réservé aux vicieux (novices s'abstenir) : créer le problème volontairement depuis une session normale de Ubuntu ")

Re : [RESOLU] ouverture session bloquée en boucle

Héhé ça marche. Je te remercie.

Pour ma culture, comment se fait-il que je n'ai eu aucun problème lors de l'installation, etc ..  et lors de l'installation du drivers NVIDIA je n'ai pu plus accéder à ma session ?

En tous cas merci pour ta réponse rapide.

La réponse la plus compacte (simple mais documentée) que j'ai trouvée est celle de Pilot6 dans ce lien : http://askubuntu.com/questions/762254/w … el-modules

Re : [RESOLU] ouverture session bloquée en boucle

Secureboot, en gros, c'est un truc qui verifie la signature numerique du kernel, c'est une sorte de securite de plus pour s'assurer de la non comprommission d'un systeme.

Par defaut, ubuntu utilise les pilotes libres (et leur modules signes) et c'est pour ca que tout fonctionnne. En revanche, lorsque tu installes le driver Nvidia proprietaire, il y a une compilation locale d'un module du kernel, qui lui ne peut pas etre prealablement signe (vu que c'est toi qui le cree lors de l'installation du driver).
De fait, le systeme est juge comme etant "compromis" et ne boot pas. Et c'est valable pour chaque truc ou DKMS entre en jeu comme virtualbox aussi il me semble.

Re : [RESOLU] ouverture session bloquée en boucle

Est-ce que le nom complet de ton modèle est ASUS GL502VS-DB71 (comme on peut voir ICI ou ) ?
Si ce n'est pas ça ce nom là, je te prie de donner le nom de ton modèle parce que je souhaiterais l'ajouter dans la Liste des portables « Asus »

Re : [RESOLU] ouverture session bloquée en boucle

Parfait.
Je viens d'ajouter ton modèle GL502VS-DB71 dans la Liste des portables « Asus ». Pour mémoire, ce modèle est équipé d'un processeur Intel Core i7-6700HQ et d'une carte graphique dédiée NVIDIA GeForce GTX 1070

Ce serait bien si tu pouvais faire un Boot-Info depuis une session de ton Ubuntu installé et donner l'URL de ce Boot-Info dans ta réponse. Cela donnerait un exemple d'installation réussie dans ce modèle pour ceux qui ont le même modèle ou un modèle approchant.

malbo,
S'il te plaît, pourrais-tu jeter un oeil là :  ./viewtopic.php?pid=21658474#p21658474
(vista + ubuntu en legacy, avec en plus des morceaux de wubi. Vista ne démarre plus ;
4.4.0-57 ; débutant).
Merci !

Ajout : Panne consécutive à un reset du BIOS.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda5, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (256GB) !

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)

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

Par ailleurs, le dual-boot semble parfait avec un démarrage par défaut sur Ubuntu.

Re : [RESOLU] ouverture session bloquée en boucle

Merci à toi de prendre le temps d'expliquer.

En tous cas, après quelques jours d'utilisation, je suis entièrement satisfait du choix de passer sous ubuntu et de ne garder windows qu'en complément.

Bonne continuation et peut-être à bientôt dans d'autres fils de discussion.
