My integrated webcam has fluctuating relationship with me[like my girlfriend- may be the reason is this fluctuating webcam]. Sometimes it works and sometimes doesnot. It sometimes work in one distro but doesnot in another. However i havenot found a way to make my integrated webcam to work in ubuntu 16.04 of my inspiron 3421. It used to work well in manjaro. In ubuntu its not working with cheese, guvcview, vlc capture, skype, viber.

i tried them

  1. Pressing all Fn+ F6-9 and see if it works in cheese/guvcview. No luck

  2. sudo chmod 777 /dev/video*

  3. lsusb -d 8087:0024 -v | grep -i "Video" sweet love of uvcdynctrl bug happened to me

android@android  :21:31:44  /var/log
--> ls -la | grep uvcdynctrl-udev.log
-rw-r--r--  1 root              root   6945067008 Aug 28 21:31 uvcdynctrl-udev.log
  1. rmmod uvcvideo then modprobe uvcvideo . No response

  2. to be continued...

If you find any duplicates for me in here please comment me.. I will try.
