Webcam is detected only when using live cd (usb boot)

[Volodya]

I have an ASUS N76V notebook. The webcam is working fine when i start with the usb stick and try to do system testing, i can see a single image and also sequantial images during the test.

However, after the installation process webcam seems to be not present. Test fails, camorama doesn't start, skype doesn't see the webcam.

(see bug 1264669)

Hi,

thank you for the new bug.

Can you attach /var/log/dmesg ?

The webcam is detected by the system

Is the package ubuntu-restricted-extras installed?

This was the problem. Thanks. It's just that during the installation it did talk about audio and video encoding that i have no need for, and didn't mention that some drivers may not work without it.
