I have a fully upgraded KDE Desktop 4.8.3 and problems with the inbuilt webcam. When I recall it correctly, the cam was working in that Laptop before, but I couldn't exactly say when that changed. When I for example check with skype, the light of the cam indicates that the program tries to access it, but it doesn't show any picture. Linphone simply crashes, when I try to deactivate the cam in the settings. The cam is not working with any software be it skype, linphone, kopete or any other picture taking application. I tried them all.
Here are the hardware spects of the cam from PCC:
Medienklasse: Video|Video Control
