No device found
I have a problem after installing cheese.
the problem I'm facing is that when I run the application it says no device found.
Next I type in the terminal box
$ cheese -v
I see webcamera default of my notebook in normal condition
seen after I typed this
$ ls /dev/video*

Next I tried to enter the preference menu
and I look at the device menu in disable state
so then I type again in the terminal box
$ sudo cheese --device=/dev/video0
