Rep:
Cannot get Chicony webcam to work on eee PC
Hello, I installed Lubuntu 14.04.01 on this netbook and I haven't been able to get the webcam to display any image.
Most threads I found while searching where from years ago with either dead links or solutions that didn't work for me.
Webcam is enabled in the BIOS and it worked with XP.

Please let me know if there is any other information that could help.
Thank you in advance
Edit:
Fixed it by disabling an re enabling the webcam in the BIOS (it was enabled under XP).
