Webcam on Lenovo U300s is not recognized by 12.04 LTS

Asked by Takashi Kawashima on 2012-09-12

I have Lenovo U300s running Ubuntu 12.04 LTS (64bit) and have noticed recently that the camera on my machine is no longer working. I have tried a couple of webcam applications and neither recognized the camera.

Cheese:
** (cheese:4237): WARNING **: cheese-window.vala:1624: Error: No device found

Camorama:
"Could not connect to the video device (/dev/video0). Please check the connection."

Can someone verify this issue?

Thanks in advance.

The output said "No LSB modules are available." Am I missing something?

No, that's normal in Ubuntu.

Can you also give the output of:

lspci

Thanks

Here you go.

It doesn't seem to be detected at all. Are there any bugs regarding the system?
Do you dual bot the system?

My apologies... it turned out to be a user error. I just noticed that F9 key was overlooked (Fn + F9 to turn on/off) -- How embarrassing!!!

Thanks a lot for the help. :)

Hi Takashi,

There is a bug[0] filed against Precise and also exists in Quantal for your model of laptop. Are you still able to use your webcam without issue? If so, can you post what kernel you are using?

Thanks in advance!
