I got my dell xps yesterday. It is the developers edition that come with ubuntu 16.04 preinstalled. 

I notice that cheese does not come installed, so I installed but no webcam is detected. I can see it if I do an lsusb, so I know is activated.

I was wondering, does this laptop supports the webcam or not?

 

Edit: Good news, a dell engineer came and replace the monitor, that has the webcam integrated and presto, it is working now.

Update: Most of the problems with the webcam is not hardware based. Looks like many of the laptops come with a firmware that the latest Linux kernel do not support at the moment. To solve the issue, Dell is replacing the whole monitor with a downgrade firmware of the webcam. If a less drastic solution is reported, I will update the post with it.

Update2: Looks like there is a software solution now.
