I have a Logitech C510 webcam connected to my desktop running 64-bit Ubuntu 11.10, but it doesn't seem to be working when I run Cheese and Skype. After doing some search, it seems this webcam should just work out of the box. However, Cheese and Skype don't seem to work with it.
I got Dell mini 910, since I upgraded from 12.04 Ubuntu to 14.04, webcam does not work with Skype. I click on Skype > option > video Devices > Select Video > integrated Webcam > (/dev/video0). When I am this point, webcam turns on and takes my photo, but as soon as I close this window, webcam shuts down, and webcam in Skype does not work. It used to work with 12.04.
