Ubuntu 18.04 lent boot (Dualboot windows 10)

Bonjour,

J'ai un PC HP neuf avec w10, j'ai installé en dual-boot Ubuntu 18.04 et il est lent au démarrage (entre 1 et 3 min) puis il a de grosses lenteurs dès que je lui en demande un peu, j'ai même les applications qui figes et demande leur fermeture. Tout devient lent alors que le monitor a une utilisation CPU à 10% et mémoire à 70%.

Dernier démarrage:

$ systemd-analyze
Startup finished in 6.682s (firmware) + 12.257s (loader) + 5.980s (kernel) + 1min 7.138s (userspace) = 1min 32.058s
graphical.target reached after 1min 7.134s in userspace

Bref lenteur anormale, ça fait 3 semaines que je cherche des solutions...

Il semblerai que parfois ce soit à cause des driver cartes graphiques, j'ai fais plusieurs tuto, installé les driver propriétaires, testé avec des versions antérieurs aussi, pas de changement (ou pire)

J'ai fini par tester le changement de noyau kernel v4.20 avec UKUU mais je n'ai pas vu de réelle amélioration ( l'écran secondaire non détecté) , je suis revenu au Linux 4.15.0.43.46

Caractéristiques:

HP 64-bit - RAM 7,6 Gio - Processeur Intel® Core™ i5-8300H CPU @ 2.30GHz × 8

carte graphique GeForce GTX 1050/PCIe/SSE2

GNOME 3.28.2

Ubuntu 18.04.1 LTS bionic

Tentes ce parametre noyau, cela ne te coutera rien d'essayer https://forum.ubuntu-fr.org/viewtopic.php?id=2035076

Je n'ai pas observé de changement en ajoutant video=SVIDEO-1:d et de même avec sudo apt-get remove xserver-xorg-video-intel cela ne fonctionne pas chez moi.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda4, using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda2/efi/.../grub*.efi !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 18.04.1 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/efi (FAT32, 100MB~250MB, en début de disque, drapeau boot). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot/efi séparée :] de [Boot-Repair].

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


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