Démarrage très lent d'Ubuntu 8-9 minutes
Bonjour,
après avoir exploré le forum, j'ai lu des problèmes similaires mais pas exactement identiques, je crée donc une nouvelle discussion.
Mon PC de bureau tourne avec Linux depuis plusieurs années, je change de distibutions régulièrement. Sans problème.
Dernièrement, mon PC met un temps très long pour démarrer : 5 minutes d'affichage du logo ASUS avec les options d'accès au Bios, puis 4 minutes de démarrage d'Ubuntu.
Si je choisis d'accéder au bios, le temps est encore plus long.
Mais une fois le PC démarré, tout fonctionne rapidement, sans problème, sauf l'application Disk de Gnome qui plante et ne démarre pas, ou bien démarre mais plante ensuite.
J'ai exploré les otions du bios, réinstallé différentes distributions, l'installation durant plusieurs heures... J'ai débranché tous mes périphériques (DD de donnée, lecteur cd) il ne reste que mon disque dur SSD NVME samsung 970 EVO.
J'ai fait un Boot-Info :
https://paste.ubuntu.com/p/cGfjCTdN8g/
Je ne comprend pas bien les propositions de réparation proposées, ni comment le faire :
Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
nvme0n1p2,
using the following options: nvme0n1p1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Quelqu'un pourrait-il m'aider en m'indiquant une marche à suivre ou un lien vers un tuto ?
Merci beaucoup
Yann

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
nvme0n1p2,
using the following options: nvme0n1p1/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 L'OS actuellement utilisé - Ubuntu 20.10 CurrentSession entry (nvme0n1p1/efi/****/shim****.efi (**** will be updated in the final message) file) !
Tout me parait normal dans ce Boot-info.
Ce qui retient mon attention dans ton post # 1 :
Si je choisis d'accéder au bios, le temps est encore plus long.
l'application Disk de Gnome qui plante et ne démarre pas
Cela me laisse à penser que c'est ton SSD qui est la cause de tout ça. Je te suggère de créer une LiveUSB de Ubuntu, de vérifier que tu parviens à démarrer une session live dessus (même si c'est long) et ensuite de déconnecter physiquement le SSD afin de vérifier si le démarrage de l'ordi sur la LiveUSB de Ubuntu est rapide ou non et si l'accès au Bios est toujours long. S'il s'avère que tout baigne quand le SSD est déconnecté, c'est qu'il est défectueux et doit être remplacé.
EDIT : au sujet des propositions de réparation proposées dans le Boot-info, il faut savoir que même si tout baigne, on voit toujours une proposition recommandée de réparation dans le Boot-info. Donc tu peux l'ignorer.

Re : Démarrage très lent d'Ubuntu 8-9 minutes
Merci pour ton aide et ta réponse. J'essaie donc de booter en live CD pour vérifier l'intégrité de mon SSD.
Je reviens vers vous dès que j'ai fait ça.

Re : Démarrage très lent d'Ubuntu 8-9 minutes
Bonjour,
Sur tes conseils, j'ai booté sur un live CD en ayant débranché mon SSD : même problème, 7 minutes d'affichage de l'a page d'option BIOS, 3 minutes de démarrage d'Ubuntu.
J'ai rebranché le SSD et booté sur une clé Boot-Repair pour réaliser les réparations recommandées.
Rien ne s'améliore.
Autres précisions : extinction du PC très longue, attente de qqch ?
Au démarrage de Gparted la première étape "searching SDA partition" très longue aussi. Logique je n'ai pas de partition SDA puisque mon disque est un SSD NVME...
Je réinstalle Ubuntu sur un autre SSD KINGSTON 300 V (pas NVME).
J'ai peur que le problème se situe sur la config du BIOS ou PB matériel de la carte mère.
Ma config :
CM ASUS Z170M PLUS BIOS ver 3805
Proc : INTEL CORE I7 6700K
Mém : Gskil RIPJAWS 4 DDR4 2x8 G 2400
DD SSD M2 SAMSUNG 970 EVO 500G
Ou SSD KINGSTON SSDNOW 300V 240Gb
Y aurait-il une option dans le BIOS pour empêcher la recherche de partition SDx et tout de suite indiquer le NVMEx ? Ou c'est le GRUB qui fait ça ?
Merci pour vos avis éclairés...
Bon week-end
Yann

Pourrais-tu prendre une photo de l'affichage de la page d'option BIOS dont il s'agite parce que je ne sais pas trop ce que tu entends par là ? Pour joindre une photo dans un post, tu trouveras des instructions dans le paragraphe 4.4 Insérer une image de la page "Aide à l'utilisation du forum Ubuntu‑FR"

OK c'est le logo Asus qui s'affiche au démarrage avec en bas de l'écran : "Please press DEL or F2 to enter UEFI BIOS setting".
Dès que tu as ça à l'écran au démarrage, si tu presses la touche "Suppr", tu vas bien dans le Bios ou pas ?

Re : Démarrage très lent d'Ubuntu 8-9 minutes
Oui quand j'appuie sur F2 j'accède au BIOS, mais c'est pas instantané, il faut 6-7 minutes...
J'ai donc réinstallé ubuntu sur un autre SSD (pas NVME mais en SATA), l'installation a duré 4h !
Avec les règlage par défaut du BIOS, je suis bien en UEFI...
Je ne sais plus quoi faire.
Des idées ?

Re : Démarrage très lent d'Ubuntu 8-9 minutes
Bonjour,
Le manuel de ta carte-mère est téléchargeable ici : https://dlcdnets.asus.com/pub/ASUS/mb/L … UM_WEB.pdf
Dans le paragraphe "1.6 Cavaliers" de ce manuel, il y a les explications pour faire un Clear CMOS. Il faudra que tu fasses toute la procédure "Pour effacer la mémoire RTC" : cette opération permet de réinitialiser les paramètres du logiciel de la carte-mère. Après cela, il est très possible que le démarrage sur ton Ubuntu installé ne fonctionne plus (on verra plus tard comment le retrouver). Par contre, tu pourras démarrer sur ton Live CD en session live. Fais-le et raconte si ça résout le problème.
EDIT : si tu es équipé d'un multimètre, ce serait utile de mesurer la tension de la pile de ta carte-mère avant de l'enlever de la carte-mère (*) : c'est une pile 3 volts. Si tu mesures moins de 2,5 volts, la pile est à remplacer : sa référence est CR2032
(*) c'est donc à faire avant d'attaquer la procédure "Pour effacer la mémoire RTC"

Re : Démarrage très lent d'Ubuntu 8-9 minutes
Non, pas la peine de refaire un clear CMOS.
J'aimerais une précision par rapport à ce que tu as écrit dans le post #1 : "Dernièrement, mon PC met un temps très long pour démarrer". C'est le "Dernièrement" qui m’intéresse : ça a commencé à se produire, il y a quelques jours, quelques semaines, quelques mois ? Et est-ce que ça a commencé doucement à se dégrader ou bien c'est apparu franchement ?

Re : Démarrage très lent d'Ubuntu 8-9 minutes
C'est venu d'un coup, et je ne vois pas à quel événement ça peut être lié. Pas de changement particulier.
Je soupçonnais mon alim, je viens de la remplacer par une neuve car la précédente montrait des signes de faiblesse et faisait un bruit d'enfer...
Pas d'amélioration avec la nouvelle pour mon problème de lenteur mais au moins plus de bruit d'alim.
J'ai dépoussiéré le PC, tout débranché rebranché...
À la fin de l'installation d'Ubuntu, j'ai eu 3 messages d'erreur au redémarrage :
X86/CPU : VMX (outsider txt) disable by BIOS
et
Failed to start ZSYS daemon services
Et
Failed to start cleanup old snapshots to free space
Avec mon ubuntu tout neuf, j'ai des messages d'erreur à l'extinction du PC :

Je ne sais pas si c'est lié au problème de lenteur...

Re : Démarrage très lent d'Ubuntu 8-9 minutes
Bonsoir,
Tout d'abord ma partition n'est plus nvme0n1p2 car j'ai fait une clean install d'ubuntu sur un autre SSD pas nvme (en SATA). Il faudrait que je vous redonne un nouveau boot-info.
Après l'installation, dans le BIOS je suis passé de l'option "Normal" à "ASUS Optimized" je pense que ça a peut-être un lien ?

Re : Démarrage très lent d'Ubuntu 8-9 minutes
Merci !
Pas de paquet btrfs-tools (qui m'avait occasionné une lenteur analogue, il y a quelques années).
Je me rappelle vaguement avoir lu quelquechose sur l'introduction de zfs, il y a déjà quelques mois. Mais où ce FS à (dé)compression intervenait-il ?
Probablement pour initramfs.
yanlatouch,
Exécute
sudo update-initramfs -u -k all ; sudo update-grub
puis chronomètre le démarrage suivant et dis-nous le résultat.
Pour le reste, je ne peux pas comparer avec ma vieille distribution.
Et ici, c'est une Ubuntu 20.10...
malbo,
Aurais-tu une 20.10 sous la main pour comparer avec les retours de yanlatouch ?
Merci !

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda2,
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: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.10 CurrentSession entry (sda1/efi/****/shim****.efi (**** will be updated in the final message) file) !

Re : Démarrage très lent d'Ubuntu 8-9 minutes
yanlatouch, ce n'est pas ce que je t'ai demandé...
J'ai executé la commande : sudo update-initramfs -u -k all ; sudo update-grub
Grosse amélioration : démarrage en 3 minutes 40, la page logo d'ASUS ne s'affiche plus que 20 secondes au lieu de plus de 6 minutes ; le démarrage d'ubuntu 20.10 met 3 minutes 20.
A l'extinction du PC, j'ai toujours des messages d'erreur :
Systemd-shutdown Waiting for process systemd-udevd
SDB : Worker 44438 processing SEQNUM:5260 is taking a long time.
Merci beaucoup, on a déjà réduit le temps de démarrage de plus de la moitié !
Yann
