Bonjour,

Je lance Bumblebee avec # bumblebeed --debug

Je lance une commande $ optirun glxspheres64

Trois modules sont chargés à l'appel de la commande optirun : nvidia <- nvidia_modeset <- nvidia_drm

Code:
n73sm ~ # lsmod
Module                  Size  Used by
nvidia_drm             38275  0
nvidia_modeset        756775  1 nvidia_drm
nvidia              11848427  1 nvidia_modeset

Quand je quitte optirun seul le module nvidia semble vouloir être déchargé par bumblebeed

bumblebeed --debug:
...

...


La carte nvidia reste en fonction :

Code:
n73sm ~ # cat /proc/acpi/bbswitch
0000:01:00.0 ON


La présence du module nvidia empêche la commande manuelle de désactivation ;
Code:
n73sm ~ # tee /proc/acpi/bbswitch <<<OFF
OFF

dmesg dit:
[ 8937.937942] bbswitch: device 0000:01:00.0 is in use by driver 'nvidia', refusing OFF


Je n'ai que ma séquence
Code:
rmmod nvidia_drm
rmmod nvidia_modeset
rmmod nvidia
tee /proc/acpi/bbswitch <<<OFF

pour éviter la consommation et la surchauffe constante.

D'où la question, comment la sortie d'une commande optirun peut-elle permettre de décharger les modules dépendant du module nvidia (nvidia_drm & nvidia_modeset) ?

Sounds like the bumblebee package was updated to use modprobe -r instead of rmmod, but your nvidia drivers package does not install module aliases required to make that work.

Code:
n73sm rem # modprobe -r nvidia
modprobe: FATAL: Module nvidia-uvm not found.
modprobe: FATAL: Error running remove command for nvidia

les modules nvidia_drm, nvidia_modeset et nvidia sont déchargés.

Après la mise à jour de bumblebee : =x11-misc/bumblebee-3.2.1_p20170123

Sans le vblank_mode=0 j'obtiens des débits vidéo similaires avec ou sans optirun ; je ne sais pas pourquoi : je ne sais pas ce qu'est cette variable vblank_mode

I'm Happy ! :)

Merci
