Situation réelle de la question

Cela ressemble beaucoup à ce qui s'est passé pour ce type Mon GPU a disparu de ma liste de périphériques. Il n'y a pas lscpi ni lshw indique la présence de la carte graphique et je ne comprends pas ce qui a causé le problème.

Informations sur le système :

  • Thinkpad P1 (2nd Gen) avec Ubuntu 20.04 qui a été mis à jour à partir de 19.10.
  • La version du noyau est la 5.4.
  • GPU NVIDIA Quadro T1000.

Le problème est apparu après une mise à jour du firmware (bios et carte mère), j'ai donc tenté un downgrade, mais fwupdmgr downgrade n'a renvoyé aucune option de rétrogradation disponible. J'ai ensuite essayé de démarrer à partir d'un live Ubuntu, et là, j'ai pu détecter le GPU et il semblait fonctionner correctement. Par conséquent, le problème ne peut pas être de type micrologiciel.

J'ai essayé de trouver des conseils utiles en matière d'erreurs en utilisant la fonction journalctl , dmesg y /var/log/syslog , sans grand succès. Si vous pensez qu'ils peuvent être utiles, je peux joindre le journal.

Je ne sais pas s'il s'agit d'un problème de module de noyau ou autre. J'ai l'impression d'avoir essayé tout ce que je pouvais sans succès. J'ai même purgé et supprimé tous les pilotes nvidia et les bibliothèques liées à nvidia, mais cela ne peut pas être la raison pour laquelle même pas lshw montre l'appareil...

P.S. L'utilisation de nvida-installer pour tenter de forcer l'installation des pilotes n'a pas fonctionné non plus.

EDIT : De nouvelles informations ont été trouvées.

En fouillant dans le journal, j'ai trouvé cette ligne :

kernel: nouveau 0000:01:00.0: DRM: Disabling PCI power management to avoid bug

(résultats complets ci-dessous [1])

J'ai donc désactivé et mis sur liste noire le pilote nouveau pour voir s'il ne faisait pas n'importe quoi, mais sans grand succès. La nouvelle sortie ne contient aucune voix concernant la désactivation de 0000:01:00.0 (qui est la carte graphique), mais elle indique seulement

kernel: pci 0000:01:00.0: Removing from iommu group 1

(sortie complète ci-dessous [2])

Mais je n'ai aucune idée de ce que cela signifie, et je n'ai rien trouvé d'utile sur le web.

Demandé dans un commentaire : Comme vous pouvez le voir, seule la carte graphique Intel est affichée :

:~$ lspci -k | grep -EA3 'VGA|3D|Display'
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile)
Subsystem: Lenovo UHD Graphics 630 (Mobile)
Kernel driver in use: i915
Kernel modules: i915

Deuxième demande :

:~$ ls -al /dev | grep nvidia
crw-rw-rw-   1 root     root    195,     0 lug  2 19:40 nvidia0
crw-rw-rw-   1 root     root    195,   255 lug  2 19:40 nvidiactl
crw-rw-rw-   1 root     root    195,   254 lug  2 19:40 nvidia-modeset

crw-rw-rw-   1 root     root    235,     1 lug  2 19:40 nvidia-uvm-tools

:~$ grep 125 /etc/group
colord:x:125:

Troisième demande : sortie de /proc/cmdline

BOOT_IMAGE=/vmlinuz-5.4.0-40-generic root=/dev/mapper/vgubuntu-root ro quiet nosplash noacpi noapic pcie_port_pm=off

Je dois préciser que la présence ou l'absence de l'une des trois dernières options n'a pas fait de différence, à l'exception de l'augmentation de l'utilisation des ventilateurs.

Veuillez consulter la réponse utile de generix ici : https://forums.developer.nvidia.com/t/no-matter-which-drivers-i-install-i-cannot-boot-my-ubuntu-20-04-lts-beyond-a-black-screen/127510/9

  1. passer à nvidia (encore) : sudo prime-select nvidia
  2. supprimer /lib/udev/rules.d/50-pm-nvidia.rules (et supprimer /lib/udev/rules.d/80-pm-nvidia.rules aussi)
  3. supprimer les fichiers de liste noire errants : sudo rm /lib/modprobe.d/blacklist-nvidia.conf /etc/modprobe.d/blacklist-nvidia.conf
  4. mettre à jour l'initrd : sudo update-initramfs -u
  5. redémarrage

Voir aussi ce message sur les forums Nvidia où generix noté :

Ok, c'est ça :

/lib/udev/rules.d/80-pm-nvidia.rules :

ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x030000", ATTR{remove}="1"

il s'agit de retirer le gpu nvidia du bus. Le reste du fichier est constitué de règles pour préparer le transfert de rendu. On dirait que quelque chose a changé dans le prime-select/nvidia-prime d'Ubuntu encore une fois, je ne sais pas vraiment quel est l'intérêt de faire ça

Pour moi, sudo prime-select nvidia fait généralement l'affaire, mais si ce n'est pas le cas, il faut supprimer manuellement le fichier /lib/udev/rules.d/50-pm-nvidia.rules y /lib/udev/rules.d/80-pm-nvidia.rules et un redémarrage devrait suffire.

Heureusement, ces règles udev disparaissent dans la version 20.10 (groovy) (voir le changelog de nvidia-prime 0.8.15), et ces problèmes de disparition de GPU Nvidia appartiendront bientôt au passé.
