i've recently installed Ubuntu 14.04 LTS x64 and cheese isn't working also skype they're recognizing the camera but it shows an error on playing from it

i tried solutions here , here and here and also no one worked for me
i have the file /dev/video0 and i tried

sudo chmod 777 /dev/video*


vlc v4l2:////dev//video0

but that's didnt work neither ,
also i tried to install guvcview but also didnt work

the output of dmesg is here , and the output of lsusb is here
and also it was working at initial install

any thoughts please ?


Install the Webcam driver packages :

sudo apt-get install build-essential linux-headers-`uname -r`

If already installed them, reconfigure them:

sudo dpkg-reconfigure -phigh build-essential linux-headers-`uname -r`
  • its already installed, and gives the error on second commnad Examining /etc/kernel/header_postinst.d. run-parts: executing /etc/kernel/header_postinst.d/dkms 3.13.0-53-generic /boot/vmlinuz-3.13.0-53-generic Error! Could not locate dkms.conf file. File: does not exist. – Waqas May 27 '15 at 13:10
