I have an xps13 ultrabook. Never had problems with cheese in 12.3. Yesterday I installed 13.1 on the xps13. Now cheese stays black. In settings, to pick the device, it is listed in gray and I cannot really change anything.

In google hangouts it works, but the image is really dark. I google chat, the webcam-picture feature freezes the image upon initialization and does not let me take one.

Is there some sort of webcam library I can use? Or should check that it is installed?
