Défilement de lignes après lancement du grub [RESOLU]

Compte supprimé · Le 19/10/2023, à 11:00

vous avez tous vu que mettre l'option splash est stupide.

C'est bien possible, mais à quoi le voit-on ?
Cela fonctionne très bien sur mon Ubuntu.

Quand à la purge, comme vu plus haut, autant aller au bout de la démarche et supprimer Grub et tous les répertoires dans EFI sauf microsoft et refind.
Et pour finir, purger la NVRAM des entrées obsolètes.
Qu'en pense geole ?

Voici les 6 icônes que j'ai.

Compte supprimé · Le 19/10/2023, à 13:50

Lesquelles de ces six icônes sont inutiles ?

Didiéridou · Le 19/10/2023, à 15:09

La 2 EFI\UBUNTU\grubx64.efi => lance grub épuré
La 3 (Fallback boot loader from no name) => lance grub épuré
La 5 vmLinuz from EOS7 => bug !
Donc je pense ôter la 3 et la 5.

Je pensais supprimer au moins ce qui concerne Mac ("My macOS" et "macOS via BootNext")
"ELILO" ???

Compte supprimé · Le 19/10/2023, à 16:09

Il n'y a aucun lien de cause à effet entre les lignes de refind.conf que tu cites plus haut et l'affichage des icônes de choix.
Ce sont des modèles en cas de configuration manuelle complémentaire. Tu as de quoi lire

Quand aux icônes en trop, c'est juste le résultat du contenu du répertoire EFI et de ton appréciation des choses.
Que veux-tu dire par "Grub épuré" ?

Je ne sais plus combien tu as de disques et d'esp, ni ce que contient l'esp du disque dont tu parles.

traduction automatique a écrit :

I : Les paramètres de ligne de commande inconnus du noyau "splash", seront transmis à l'espace utilisateur.

J'en déduis que ce n'est pas traité. Donc c'est inutile de se fatiguer à écrire le mot. Je pense qu'il n'y a pas de faute d'orthographe. Cette option est désuète.

Tant que tu as ce mot disable, le menu n'est pas affiché. Ce sont des exemples pour le traitement des cas que refind n'a pas prévu. Un cas d'utilisation est lorsqu'on doit se servir du fichier de boot de windows pour lancer les ubuntu, on se sert d'une de ces commandes pour lancer alors windows.

Ton cas est simple. Cela se traite avec décommentant des lignes en amont.
Voici un exemple qui élimine des lignes.
dont_scan_files shim.efi,MokManager.efi,bootx64.efi
éventuellement
dont_scan_files shim.efi,MokManager.efi,bootx64.efi,grubx64.efi
ainsi que
dont_scan_volumes "Recovery HD" ou tu remplacerais "Recovery HD" par l'étiquette qui est allouée à la partition EOS7.
Je voudrais d'ailleurs comprendre pourquoi cela ne fonctionne pas.
Tu as encore cette possibilité des répertoires. L'exemple commenté est
#dont_scan_dirs ESP:/EFI/boot,EFI/Dell,EFI/memtest86
mais je ne sais plus comment on mets plusieurs répertoires de plusieurs partitions

J'aimerai bien n'en avoir que trois ou quatre comme avec le grub épuré.

Que veux-tu dire par "Grub épuré" ?...

Windows + Ubuntu + EOS7

J'avais cru comprendre que c'était dans ce fichier (refind.conf) qu'on pouvait choisir quoi afficher ???
Dans ce fichier j'ai remarqué cette ligne qui est décommentée:
use_nvram false

@Didiéridou
A ce stade, le mieux serait que tu regardes la documentation disponible si tu veux affiner le fonctionnement de tes outils.
Bien entendu, si après étude de la documentation disponible, il reste des points à éclairer, on essayera de répondre à tes questions.

Et, pour mon instruction, quel est l'intérêt d'avoir EOS ? J'imagine qu'il fait des choses utiles qu'Ubuntu ne sait pas faire.

Il est plus "léger" et, hormis les forums qui ne sont pas tout à fait à la hauteur de tous ceux de Ubuntu , ça tourne plutôt pas mal. et basé sur Ubuntu

Cela me rassure que quiet splash ne soit pas mis en automatique, je commençais à avoir un doute pour ma vieille version.

Alors tu peux t'inquiéter car j'avais testé sur une Ubuntu 23.10 et je viens de refaire pour être certain.
J'ai désinstallé rEFInd et supprimé le répertoire /boot/efi/EFI/refind ainsi que le fichier /boot/refind_linux.conf.

A la suite de quoi, j'ai installé refind et voilà :

toto@toto-VirtualBox:~$ sudo cat /boot/refind_linux.conf
"Boot with standard options"  "ro root=UUID=da0f834c-30cc-484c-b805-a3cf81b0ec53 quiet splash"
"Boot to single-user mode"    "ro root=UUID=da0f834c-30cc-484c-b805-a3cf81b0ec53 quiet splash single"
"Boot with minimal options"   "ro root=UUID=da0f834c-30cc-484c-b805-a3cf81b0ec53"

Je suis en plein test 22.10 d'installation sur un disque USB, J'ai booté avec et y ai installé refind
Effectivement le contenu est le suivant

cat /mnt/boot/refind*
"Boot with standard options"  "root=UUID=de697384-0095-4e7a-8efe-b9a12999a833 ro quiet splash vt.handoff=7"
"Boot to single-user mode"    "root=UUID=de697384-0095-4e7a-8efe-b9a12999a833 ro quiet splash vt.handoff=7 single"
"Boot with minimal options"   "ro root=UUID=de697384-0095-4e7a-8efe-b9a12999a833"

Sans l'avoir regardé, j'ai viré le refind que j'avais, cela a pris un peu temps, car il était à plein d'endroits, Je l'ai réinstallé dans mon le ubuntu 22.04,
Mais j'avais oublié de supprimer la configuration. Elle est donc restée ce que j'avais. Attention les yeux.

"Boot with standard options"  "root=UUID=79cea674-14f7-4780-b5a3-898dd31ec6b2  ro loglevel=3"
"Boot to single-user mode"    "root=UUID=79cea674-14f7-4780-b5a3-898dd31ec6b2  ro single debug ignore_loglevel "
"Boot with minimal options"   "ro root=UUID=79cea674-14f7-4780-b5a3-898dd31ec6b2 nomodeset debug ignore_loglevel"
"Boot with standard options"  "root=UUID=79cea674-14f7-4780-b5a3-898dd31ec6b2 nomodeset ro loglevel=3"

"Boot with minimal options"   "ro root=UUID=79cea674-14f7-4780-b5a3-898dd31ec6b2 nomodeset debug ignore_loglevel

manifestement, j'ai oublié le mot recovery.

Pour Didiéridou
Pour modifier le fichier

gedit admin:///boot/efi/EFI/refind/refind.conf

Puis tu ajoutes cette première ligne en mettant les noms des labels des partitions que tu ne veux pas faire examiner à la place de mes deux noms
dont_scan_volumes "SAVECOMMUN","Data"
Tu peux les obtenir avec cette commande sudo blkid
et cette ligne
dont_scan_dirs /EFI/boot,EFI/ubuntu,EFI/memtest86
Du coup, tous ces répertoires ne seront pas examinés. Au besoin, tu peux en ajouter. Mais il faudrait savoir lesquels.
N'oublie pas de sauver avant de quitter.

Bon ce n'est pas que je ne veux pas les examiner mais seulement je ne veux pas voir les lignes défiler ...

Compte supprimé · Le 20/10/2023, à 09:45

De quelles lignes est-il question ?
Les informations que te donne geole sont relatives à la suppression des icônes que tu ne veux pas afficher sur la fenêtre de choix de rEFInd, les six icônes.
Pour qu'elles disparaissent, il faut dire à rEFInd de ne pas en tenir compte, ne pas aller les lire ou lire dans les répertoires concernés.
Une autre solution plus radicale consisterait en la suppression de Grub, memtest et tout ce qui te gène. Il ne te resterait que trois icônes, une par OS.

Par contre pour le défilement des lignes au démarrage, et maintenant que l'option quiet est en place, s'il y a des erreurs au boot, tu verras quand-même des lignes défiler tant que les erreurs ne seront pas corrigées.

D'autre part, j'ai vu plus haut que tu as une partition "home commun", c'est juste un label ou tu montes vraiment la même partition dans /home sur les deux OS ?

Je voudrais garder un lancement possible vers Windows, Ubuntu et EOS7.
Dans l'ordre de gauche à droite j'ai:
1-Boot Microsoft EFI boot from System (Windows sans doute ??? si oui donc à garder) "/dev/sda1: LABEL="SYSTEM" UUID="0CED-EBAB" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="SYSTEMFAT32bootESP" PARTUUID="0a97e305-2f2d-452e-8be8-acc821e1b4c9"
ou
/dev/sda3: LABEL="Systeme" BLOCK_SIZE="512" UUID="A098FA2398F9F81C" TYPE="ntfs" PARTUUID="8c325e9e-7f85-4ea6-a2ce-ad822ed18c9b"

2-BootEfi\Ubuntu\grubx64.efi from boot,esp (=> celle-là lance le grub) "/dev/sdb1: UUID="C483-DBB3" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="boot,esp" PARTUUID="5ae5d080-5a1f-4160-b102-99ea06a8e47a"

3-Boot Fallback boot loader from boot,esp (=> celle-là aussi lance le grub)??? "/dev/sdb3: UUID="a847127f-af2f-495d-9114-a0f708e54732" BLOCK_SIZE="4096" TYPE="ext4" PARTLABEL="UBUNTU" PARTUUID="6100e446-6d3b-4464-bc3b-2ab18243b6fb" c'est celui-là?
4-Boot \vmLinuz-5.15.0-86-generic from Ubuntu (=> à garder) ou celui-là ?
5-Boot vmLinuz from EOS7 (=> à supprimer) ???
6-Boot boot\vmLinuz-6.2.0.34-generic from EOS7 (à garder) "/dev/sdb5: LABEL="EOS7" UUID="e441a19f-0001-4d1e-8e73-5c401fd2f5ec" BLOCK_SIZE="4096" TYPE="ext4" PARTLABEL="ELEMENTARY07" PARTUUID="bf5ae3ef-bfa1-438e-992a-1b1deb4fcbfe"

Quant au "homecommun" c'est surtout que je veux y avoir accès depuis les deux distrib LINUX mais il n'est pas reconnu directement comme 'home" dans EOS7.
Autrement dit c'est le home Ubuntu qui se nomme homecommun.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub-efi of
sdb3,
using the following options:  sdb1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.3 LTS entry (sdb1/efi/****/grub****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi (**** will be updated in the final message)

Bonjour Xubu1957
Quand j'ai vu le nombre de lignes je n'ai pas osé les copier/coller...
