[RÉSOLU] Démarrage lent depuis mise à jour vers 18.04

Bonjour tout le monde,

Je suis sur Ubuntu Mate et j'ai fait récemment la mise à jour de 17.10 à 18.04 et depuis le démarrage est deux fois plus long.

Quand j'exécute la commande

systemd-analyze time

, je peux voir que le noyau met 34 secondes à se charger.

De plus, quand je fais un démarrage en mode verbeux, je peux voir que l'ordinateur passe beaucoup de temps à la ligne

Clocksource: switched to clocksource tsc

.

Je n'ai pas trouvé beaucoup d'information sur cette question jusqu'à maintenant et je me demande si je ne suis pas tombé sur un bug dans le noyau.

Merci à l'avance de votre aide!

Re : [RÉSOLU] Démarrage lent depuis mise à jour vers 18.04

Bonjour,
Je te prie de faire un Boot-Info depuis une session de ton Ubuntu 18.04 en suivant les indications de la partie Cas où au moins un ubuntu installé sur disque est opérationnel du paragraphe 1.1 Installation, puis en lançant Boot-Info suivant 1.2 Utilisation. Tu donneras 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 sdc2, using the following options:        sdc1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sdc1/efi/.../grub*.efi file!

If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS 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


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

Je crois qu'il faut que tu commentes la ligne suivante de ton fstab :

/dev/mapper/cryptswap1 none swap sw 0 0

C'est à dire que tu ajoutes le caractère # en tête de cette ligne afin qu'elle soit considérée comme un commentaire :

#/dev/mapper/cryptswap1 none swap sw 0 0

Pour modifier le fichier fstab avec pouvoir administrateur à l'aide de gedit, tu peux utiliser la commande suivante (source) :

gedit admin:///etc/fstab

N'oublie pas d'enregistrer dans gedit avant de quitter.

Re : [RÉSOLU] Démarrage lent depuis mise à jour vers 18.04

Je pense que ma proposition du post #4 n'est pas bonne (ou plutôt qu'elle doit venir en complément de ce que je vais expliquer). Je viens de trouver cette page qui doit mieux convenir. On y voit le même symptôme que celui que tu as signalé ( " je peux voir que l'ordinateur passe beaucoup de temps à la ligne "clocksource: switched to clocksource tsc") et il y a la description de la solution qui a fonctionné :
--------------------------------------------------------------------------------------------
I modified this file: /etc/initramfs-tools/conf.d/resume. In this file, a line with RESUME=none (instead of the UUID that was here) will disable waiting for a resume device.

Run sudo update-initramfs -u to apply the changes.

System now boots normally
----------------------------------------------------------------------------------------
Pour modifier ce fichier, tu peux passer cette commande :

gedit admin:///etc/initramfs-tools/conf.d/resume

Je ne sais pas pourquoi mais chez moi, mon mot de passe est demandé deux fois avant que gedit veuille bien se lancer.

Alors c'est cette dernière manip qui règle le problème. Maintenant, le noyau se charge en deux secondes.

Merci beaucoup malbo!

Re : [RÉSOLU] Démarrage lent depuis mise à jour vers 18.04

Bonne nouvelle !
Pour moi, la cause du problème c'est que tu avais adopté le chiffrage de ton dossier personnel dans ton 17.10 (peux-tu confirmer ? ) et que ça a merdé lors de la mise à niveau parce que 18.04 ne doit pas permettre le chiffrage du dossier personnel.

Re : [RÉSOLU] Démarrage lent depuis mise à jour vers 18.04

Oui, j'avais chiffré mon dossier personnel dans la 17.10.

Si je ne me trompe pas, avec la 18.04, Ubuntu propose le chiffrage complet du disque?

Re : [RÉSOLU] Démarrage lent depuis mise à jour vers 18.04

Oui, j'ai vu ça dans ce paragraphe des "release notes for Ubuntu 18.04" : https://wiki.ubuntu.com/BionicBeaver/Re … _16.04_LTS :
------------------------------------------------------------------------------
The installer no longer offers the encrypted home option using ecryptfs-utils. It is recommended to use full-disk encryption instead for this release. (1756840)
------------------------------------------------------------------------------
C'est la foutue case à cocher "Chiffrer la nouvelle installation de Ubuntu pour la sécurité" proposée à l'étape 3 de l'installation. Cette fonctionnalité est une grosse daube et je déplore que des novices se fassent prendre par ce baratin et cochent cette case.
