Thanks for the quick feed back, but i am a real beginner on Linux, so i don't know how to get the requested infos. If u could give me the command to run or where to look ?
Here also u will see the output in the terminal when i launch cheese :
** Message: cheese-application.vala: Error during camera setup: Aucun périphérique détecté
(cheese): cheese-CRITICAL **: cheese_camera_device_get_device_node: assertion 'CHEESE_IS_CAMERA_DEVICE (device)' failed
