======= Le portable Dell™ Vostro 3n60 ======

Cette page concerne les modèles Vostro 3360, 3460 et 3560, délivrés par Dell, au premier semestre 2012.

===== Lecteur d'empreintes digitales non reconnu =====

Voici la signature du lecteur d'empreintes digitales (via lsusb):
<code>
Validity Sensors, Inc. VFS5011 Fingerprint Reader
</code>

Il n'existe à l'heure actuelle aucune possibilité de lire des empreintes digitales venant du lecteur VFS5011 grâce à la librairie libfprint. Une version ultérieure en donnera peut-être la possibilité. {NDLR : date ?}

Code source du fichier-test "validity.c" de la puce Validity Sensors 138a:0050 équipant les ordinateurs Dell et HP Envy. {NDLR : au 3 juin 2016}

===== Ventilateur à vitesse maximum =====

Problème rencontré sur Vostro 3460 et 3560 (à confirmer pour le Vostro 3360). Le ventilateur (fan) tourne à vitesse maximum tout le temps, même lorsque la température des ventilateurs ne le justifie pas ( < 60° ).
La configuration de lm-sensors ne permet pas d'afficher la vitesse réelle des ventilateurs (à l'aide de la commande "sensors")

==== Solution (Workaround) ====

(source : [[:dell_inspiron_6400#controler_la_vitesse_des_ventilateurs]])

I8k est un utilitaire permettant la contrôle des ventilateurs et la supervision de la température des processeurs.
Son installation se fait par la simple installation du paquet **[[apt>i8kutils]]** 
Ajoutez alors le module i8k:

<code>sudo modprobe i8k</code>

Voici alors les commandes utilisables:

<code>i8kfan  ### Permet d'afficher le niveau de vitesse courant du ventilateur. Si votre ventilateur fait beaucoup de bruit, la valeur est alors à "3".</code>

<code>i8kmon  ### Permet d'afficher le panel de contrôle de la vitesse des ventilateurs. Essayez de switcher entre les valeurs "", "1", "2" et "3" dans la case du bas pour entendre la différence de vitesse de rotation des ventilateurs.</code>

== Paramétrage et automatisation ==

Pour éviter d'avoir à recharger le module "i8k" à chaque démarrage, ajoutez le dans le fichier /etc/modules avec:
<code>echo "i8k" >> /etc/modules</code>

Ensuite, autorisez le démarrage du daemon en modifiant le fichier /etc/default/i8kmon et en passant la valeur "1" au paramètre ENABLED.

Finalement, créez le fichier /etc/i8kmon.conf et insérez-y les valeur suivantes:

<code># Run as daemon, override with --daemon option
set config(daemon)      1

# Automatic fan control, override with --auto option
set config(auto)        1

# Status check timeout (seconds), override with --timeout option
set config(timeout)     2

# Temperature thresholds: {fan_speeds low_ac high_ac low_batt high_batt}
set config(0) {{- 0} -1 45 -1 45}
set config(1) {{- 1} 40 60 40 60}
set config(2) {{- 2} 55 125 55 125}
set config(3) {{- 2} 70 128 10 128}

# end of file</code>

Ces valeurs peuvent être modifiées selon vos désirs.

Enfin, vous pouvez ajouter le lancement du script i8kmon au démarrage grâce à un simple:
<code>update-rc.d i8kmon enable</code>

Après redémarrage, les ventilateurs devraient être presque silencieux, et la température des CPU, supervisé pour un meilleur rendement énergique, et aussi pour le plaisir de vos oreilles!
