Webcam intégrée ne fonctionne pas sous Ubuntu 20.04

sidran

Bonjour,

Ma webcam intégrée ne fonctionne plus depuis que je suis passé à Ubuntu 20.04 comme seul système d'exploitation installé. J'ai essayé de trouver une solution dans la documentation, mais j'avoue être un peu perdu.

Dans l'invite de commande j'ai tapé

lsusb

Et voici ce que j'obtiens:

➜  ~ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2b Intel Corp.

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Est-ce qu'une âme charitable aurait une idée du problème?

Bonjour,

Dans la notice de l'ordi, quelles sont les consignes pour activer la webcam ?

Montre, en te servant du Retour utilisable de commande :

lsusb | sort; echo; lsusb -t

lsmod | sort

dmesg | grep -i usb

En lançant en commande :

webcam

ressort-il un message ?

sidran

Merci pour ta réponse.

Lorsque j'étais en dual boot avec ubuntu la webcam fonctionnait sans pb, je n'ai jamais eu besoin de l'activer. Je suis en train de consulter la doc de mon asus pour voir ce qu'ils disent là-dessus

Voici les retours de commande demandés:

Tente :

sudo modprobe -r uvcvideo && sudo modprobe uvcvideo

sidran

J'ai tenté

sudo modprobe -r uvcvideo && sudo modprobe uvcvideo

Il y a du mieux puisque dorénavant j'ai accès aux paramètres vidéo de zoom (ce qui n'était pas le cas avant) mais l'écran de la cam est noir.
Lorsque je lance cheese le message d'erreur suivant s'affiche: "une erreur est survenue pendant la lecture de la vidéo de la webcam" 🙁

xubu1957

Tu devrais essayer avec [doc]guvcview[/doc].

sidran

J'ai téléchargé guvcview, mais pas de changement...

xubu1957

En lançant en commande :

guvcview

ressort-il un message d'erreur ?

_ _ _

Pour cheese, dans > [résolu] Le programme Cheese ne fonctionne plus ...

> bugs.launchpad.net/ubuntu/+source/cheese/+bug/1295247 ?

WORKAROUND: In Cheese preferences lower image resolution to 640x480.

SOLUTION DE CONTOURNEMENT : dans les préférences de Cheese, réduisez la résolution de l'image à 640 x 480.

_ _ _

Allez dans les préférences de cheese et réglez la résolution de la photo et de la vidéo sur une valeur plus basse, par exemple 640x480, et redémarrez Cheese. Est-ce que cela règle le problème? -

Le 25/06/2018, pseudofab a écritBonjour Xubu1957,
Effectivement en baissant la résolution cela marche. 😉
Bizarre je n'ai pas souvenir d'avoir un jour touché aux paramètres...
Merci pour ton aide .

Je vais faire la manip dans cheese

J'ai vérifié dans Cheese, la résolution de l'image était déjà à 640 x 480

Ton Asus, c'est quel modèle, pour cibler des recherches ?

sidran

c'est un Asus ZenBook UX410U

xubu1957

Tu as regardé les options du BIOS ?

xubu1957

Un retour avec :

ls -la /dev/video?

?

Je suis allé faire un tour dans le BIOS, je n'ai pas trouvé d'infos sur la caméra...
Voici le retour utilisable de commande:

➜  ~ ls -la /dev/video?

Tente cette commande, pour les permissions :

echo -e "\n\tNombre d'éléments de /home/moi ne m'appartenant pas :"; find ~ \( ! -user $USER -o ! -group $USER \) | wc -l

Je suis en manque d'idées.
