[Nvidia & Xorg/PRIME] Impossible de démarrer sur la carte Intel et utiliser GPU Nvidia

[BlondVador]

Bonjour,

Je suis passé, il y a quelques semaines de ça, de Bumblebee à Nvidia avec le support d'Optimus (mais pas du switch GPU) qui est apparut depuis. Gros plus : j'ai constaté un gain de performance allant jusqu'à x3 dans certain jeux !

Seulement, je tourne directement sur la carte Nvidia et j'aimerai l'utiliser uniquement quand je lui demande.

J'ai essayé avec bbswitch en standalone, sans résultat. Je suis finalement tombé sur PRIME :
https://wiki.archlinux.org/index.php/PRIME

J'ai essayé diverses manipulations, j'arrive à démarrer sur la carte Intel mais il m'est impossible d'utiliser le GPU Nvidia.

Auriez-vous une idée s'il vous plaît ?

Je vous transmets ici les informations nécessaires :

Je vois les 2 providers si je démarre sur le GPU Nvidia.

Code : Tout sélectionner

[perru@perru ~]$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x2b2 cap: 0x1, Source Output crtcs: 0 outputs: 0 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x46 cap: 0x2, Sink Output crtcs: 3 outputs: 4 associated providers: 1 name:modesetting

Je n'en vois qu'un seul si je démarre sur le GPU intel (le module n'est pas blacklisté) :

PRIME est incompatible que je sache avec les drivers propriétaires.

[BlondVador]

C'est ce que j'ai cru comprendre sur le wiki Arch effectivement, cependant sous Ubuntu ils ont un petit soft nommé nvidia-prime qui semble fonctionner. J'ai trouvé un PKGBUILD qui est censé permettre l'installation de nvidia-prime. L'installation fonctionne mais ça s'arrête là, aucun outil ne fonctionne. Je suis bien conscient que c'est le PKGBUILD récupère le paquet pour Ubuntu mais l'auteur semble indiquer que son script fonctionnait en date du 11 février 2015.

Une fois que tu as démarré avec la carte nvidia, si tu utilises nvidia-settings, tu n'as pas un "onglet" prime ?

[BlondVador]

Non, cependant j'ai bien de nouvelles entrées possibles dans le terminal telles que "prime-select intel|nvidia|amd". Il semble y avoir quelques soucis avec le script cependant :

Code : Tout sélectionner

[root@perru perru]# prime-select intel
Traceback (most recent call last):
  File "/usr/sbin/prime-select", line 345, in <module>
    switcher = Switcher()
  File "/usr/sbin/prime-select", line 141, in __init__
    int(not self._supported_architectures
AttributeError: 'dict_values' object has no attribute 'index

Code : Tout sélectionner

[root@perru perru]# prime-switch 
/usr/sbin/prime-switch: ligne 22: /usr/bin/gpu-manager: Aucun fichier ou dossier de ce type

J'ai essayé de trouver gpu-manager sur AUR, sans résultat. J'ai plus l'impression que c'est un problème de dépendance plus qu'autre chose.

Je suis tombé sur un sujet qui semblait intéressant mais incomplet également :
https://bbs.archlinux.org/viewtopic.php?id=194947

EDIT :
J'ai réussi à avancer un peu en utilisant python2 :

Code : Tout sélectionner

[root@perru perru]# python2 /usr/bin/prime-select intel
Info: the current alternatives in use are: [None, None]
Error: the installed packages do not support PRIME
Error: intel mode can't be enabled

J'ai zyeuté rapidement mon /usr/bin/prime-select, je vous le dépose ici si jamais :

De ce que j'ai compris, le script switch du pilote libre nouveau pour la carte Intel au pilote proprio nvidia pour le GPU Nvidia. Etant donné qu'on ne peut avoir qu'un seul des deux pilotes sous arch à cause d'un conflit, je pense qu'on peut abandonner l'idée de ce petit script...

Je continue de fouiller le web à la recherche d'une piste mais étrangement, il ne semble pas il y avoir beaucoup d'archeux intéressés par une telle fonctionnalité... Dommage. Je pense qu'il faut adapter nvidia-prime pour arch. Je vais voir ce que je peux faire de mon côté et je proposerai un PKGBUILD sur AUR si j'arrive à quelque chose.

Le topic reste d'actualité, si jamais quelqu'un a une idée .

EDIT 2 :
J'ai trouvé ce thread sur les forums anglais :
https://bbs.archlinux.org/viewtopic.php?id=177945

Le dernier post donne une procédure intéressante :

Switch to Intel:
-kill lightdm (login manager)
-rmmod nvidia
-echo "OFF" >> /proc/acpi/bbswitch
-Switch xorg.conf over to Intel version (Probably don't need one)
-start lightdm

Switch to Nvidia:
-kill lightdm
-modprobe nvidia
-echo "ON >> /proc/acpi/bbswitch
-Switch xorg.conf over to Nvidia version
-start lightdm

Du coup j'ai voulu me faire un petit script bash pour essayer :

Code : Tout sélectionner

systemctl stop lightdm.service& rmmod nvidia& tee /proc/acpi/bbswitch <<<OFF& cp /etc/X11/xorg.conf.bak-empty /etc/X11/xorg.conf& systemctl start lightdm.service

Le soucis c'est que ça ne relance pas ma session. Cependant si je reboot, je suis bien sur la carte Intel (évidemment puisque le xorg a changé). Comment pourrai-je faire ça "on the fly" ?
