ordi qui passe en veille

[mat]

J'ai fait la manip pour la mise à jour du noyau.
Dans la liste proposée, je n'avais pas le 4.7. Du coup, j'ai tenté le 4.9.
Le résultat est la disparition de l'erreur au démarrage :
"via-ircc 0000:00:11.0: can't enable device: BAR 13 [io 0x4000-0x407f] not claimed"
Par contre les lignes précédentes y sont.

Voilà ce que j'ai obtenu avec les manip de Philippe :
Les commandes xset ont produit des messages d'erreur que j'ai laissés à la suite. Et malheureusement, pas de changement côté mise en veille intempestive...
