Archisman Panigrahi, to further clarify your comment: >"external Logitech C170 does not work in desktop."
Are you stating the external Logitech C170 does not work when plugged into the laptop? Also, could you please provide the full laptop model as noted on the sticker of the computer itself? ** Description changed: - Whenever I open Cheese in Ubuntu 14.04 beta 1 (Unity), my webcam's light once turns on, then it turns off and Cheese turns black, written "There was an error playing video from webcam". This never happened in any previous versions of Ubuntu. + Whenever I open Cheese in Ubuntu 14.04 beta 1 (Unity), my external Logitech C170 webcam's light turns on once, then it turns off and Cheese turns black, written "There was an error playing video from webcam". This never happened in any previous versions of Ubuntu. The problem is reproducible.
