Notebook Dell N5010+cam+amsn = doesn't work

Hi folks,

I'm trying to finding the solution for my problem, but it's impossible.
I've read various topics about this subject , unfortunately, nothing.

I run the command amsn in terminal and configure video in preferences of amsn.
The messages is shown below:

At the end of the configuration, the amsn displays a message saying: "Checking if Farsight extension is loaded...X"

What can I do ??

Thank you
