Support Debian
#1

Bonsoir, je suis relativement nouveau sur Debian et j’éprouve un problème avec ma caméra intégré.
J’aimerais vos conseils et votre aide pour la faire fonctionner. Elle fonctionnait adéquatement il y a deux jours en chargeant le pilote uvcvideo mais depuis que j’ai redémarré elle n’est plus reconnue.

Salut,

Tu peux vérifier si le fichier /dev/video0 existe, ce serait bon signe.

Par contre, je vois pas quel est le modèle de ta cam parmi ces infos.

… pourrait aider. Il doit y avoir quelques lignes qui concernent le module uvcvideo.

Si ton ordi est un portable, vérifie que tu n’as pas une touche FN+qqch pour dés(activer) ta webcam.

#3

Non, effectivement lorque j’ai vérifié je n’avais pas ce fichier /dev/video0.
Je vous ferai une copie du résultat dmesg dès que je serai de retour à la maison ce soir.

Concernant FN + quelque chose je vais essayer ça aussi, j’avoue que c’est logique.
Mais savez vous est-ce que je peux trouver la liste des racourcis clavier pour les évênements spéciaux.

Merci :slightly_smiling:

#4

Les touches FN+qqch, elles sont visibles sur ton clavier de portable, vu que ça dépend du constructeur. Donc si on veut trouver cette info ailleurs, faut se renseigner sur les modèles d’ordi, mais bon, sinon suffit de regarder son clavier :stuck_out_tongue: Chez moi elles sont indiquées en bleu.

#5

Évidemment, je vais testé ça dès mon retour, à ce que je peux voir en ligne pour mon AlienWare c’est FN + F9
Merci encore de l’attention particulière que vous portez à mon problème. :041

#6

Donc effectivement depuis que j’ai fait FN+F9 ma WebCam est listé dans ChesseCam mais elle n’affiche qu’un écran noir.
