Je tente de résoudre ce petit soucis quand même, ce n'est pas grave si je n'ai pas de réponse, si j'arrive à trouver une potentielle réponse qui puisse aider d'autres personnes plus tard, tant mieux 
J'essaye d'exécuter des commandes (pas n'importe lesquelles quand même) sur la partie GPU pour voir si c'est supporté :
