[Résolu] GRUB_CMDLINE_LINUX="nomodeset" après install en mode non-EFI

J'ai créé cette discussion pour tenter de comprendre d'où vient la ligne GRUB_CMDLINE_LINUX="nomodeset" qu'on peut trouver dans une installation de Ubuntu faite en mode non-EFI (mode Bios classique). J'ai trouvé le cas dans cette discussion et ça m'a donné envie de faire les essais suivants en virtualisation (avec VirtualBox)

1) Démarrage en session Live de Ubuntu 16.04.2 64 bits avec le paramètre de noyau nomodeset sélectionné suivant cette procédure : https://forum.ubuntu-fr.org/viewtopic.p … 1#p8087381
Arrivé sur le bureau en session live, je passe la commande "cat /proc/cmdline" pour vérifier comment sont prises les options :

ubuntu@ubuntu:~$ cat /proc/cmdline
file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash ---  nomodeset debian-installer/language=fr keyboard-configuration/layoutcode?=fr keyboard-configuration/variantcode?=oss
ubuntu@ubuntu:~$ 

Je crois que ça sent déjà le brun : l'option nomodeset apparaît après les trois tirets et à mon avis, ça signifie que l'option nomodeset va être "injectée" dans le Ubuntu installé.

2) Depuis la session live, je lance l'installation par l'icône de l'installateur qui se trouve sur le bureau.
3) Après installation, redémarrage sur le Ubuntu installé.
Voici le Boot-Info réalisé depuis la session du Ubuntu installé :

=================== 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


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

Ce que je craignais est bien là. On voit la "signature" du problème dans cet extrait de la partie /etc/default/grub du Boot-Info :

GRUB_CMDLINE_LINUX="nomodeset"

Avec les conséquences de cette anomalie : toutes les entrées du menu Grub sont avec cette option nomodeset, en particulier l'entrée par défaut du menu Grub comme on peut voir dans cet extrait :

BOOT_IMAGE=/boot/vmlinuz-4.8.0-36-generic root=UUID=55e0e0b9-924a-4977-9dfb-b5bde566387d ro nomodeset quiet splash

Re : [Résolu] GRUB_CMDLINE_LINUX="nomodeset" après install en mode non-EFI

Pour voir si ça existe depuis longtemps cette blague, je fais la manip avec Ubuntu 12.04.1 64 bits 

1) Démarrage en session Live de Ubuntu 12.04.1 64 bits avec le paramètre de noyau nomodeset sélectionné suivant cette procédure : https://forum.ubuntu-fr.org/viewtopic.p … 1#p8087381
Arrivé sur le bureau en session live, je passe la commande "cat /proc/cmdline" pour vérifier comment sont prises les options :

ubuntu@ubuntu:~$ cat /proc/cmdline
file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash --  nomodeset debian-installer/language=fr keyboard-configuration/layoutcode?=fr keyboard-configuration/variantcode?=oss
ubuntu@ubuntu:~$

2) Depuis la session live, je lance l'installation par l'icône de l'installateur qui se trouve sur le bureau.
3) Après installation, redémarrage sur le Ubuntu 12.04.1 64 bits installé.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


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

Là, on peut constater que contrairement au post #1, l'option nomodeset n'a pas été injectée dans le Ubuntu installé (on voit seulement nomodeset pour l'entrée "Ubuntu, avec Linux 3.2.0-29-generic (mode de dépannage)" mais c'est normal parce que l'entrée pour le mode de dépannage est toujours avec ce paramètre).

Re : [Résolu] GRUB_CMDLINE_LINUX="nomodeset" après install en mode non-EFI

Injecter des param live dans l'installe n'est pas si con pour autant que par la suite, l'ajout de pilotes proprio (si c'est la raison de l'usage de ces param) rectifie le grub, non ?

Bref, ça sent la bonne idée "cooool", mais sans suivi, ou au suivi encore plus complexe à réaliser.


Gaulois Matter !

Re : [Résolu] GRUB_CMDLINE_LINUX="nomodeset" après install en mode non-EFI

J'ai fait des essais complémentaires et il ressort que jusqu'à Ubuntu 12.10, ça se passe comme pour Ubuntu 12.04.1 (post #2), c'est à dire qu'après installation, on n'a pas nomodeset qui est "injecté" dans Ubuntu installé. Par contre, j'ai vérifié que pour Ubuntu 13.04 et Ubuntu 14.04.1, ça se passe comme pour Ubuntu 16.04.2 (post #1). Je n'ai pas le courage de vérifier chaque version intermédiaire mais je suppose qu'à partir de Ubuntu 13.04 et pour toutes les versions suivantes, on se retrouve avec "GRUB_CMDLINE_LINUX="nomodeset" dans le fichier /etc/default/grub après installation. Ce qui implique que ce paramètre est appliqué à toutes les entrées du menu Grub sauf les entrées pour les autres install (Windows ou autres Linux).

J'ai détaillé la solution pour virer nomodeset dans ce post : https://forum.ubuntu-fr.org/viewtopic.p … #p21720623
