I have a webcam on Ubuntu 11.10 which was working well in Cheese, Skype and Motion.
I rebooted the PC, and now the webcam doesn't work. Cheese hangs with a blank screen and no menus or elements on the screen. VLC doesn't display anything.
With motion, there is no output and no webcam output.
With lsusb I get:
Bus 002 Device 003: ID 0c45:60c0 Microdia PC Camera with Mic (SN9C105)
What is wrong? How do I get it working again?
Many thanks for your help.
