To sivakumar,<br><br>Is your laptop a netbook ?(just curious) <br><br>When you say the camera isn't working do you mean that you've tried it with some video conernecing software and it wasn't detected ? Ubuntu doesn't list the webcam under Computer like windows does. So your webcam may be detected and working.<br>
<br>If you haven't tried it with any software install the program 'cheese'. You can see the webcam feed and take pictures and videos through that. If it works then great although there may be some problems with video conferencing applications(like skype). <br>
<br>If no webcam is detected by 'cheese' then your webcam may or may not be getting detected. In that case get the output of the 'lspci' or 'lshw' command and put them up on some forum site such as <a href="http://ubuntuforums.org">ubuntuforums.org</a> and ask for help.<br>
