I installed my Ubuntu 14.04 LTS alongside my Windows system. It's a ThinkPad E555 laptop. I just tried to use Skype and Google Hangouts today but could not get my built-in webcam to work. I would like to be able to use my webcam so please help if you can! Thank you very much!

I ran cheese and it shows "No device found":

** Message: cheese-application.vala:291: Error during camera setup: No device found
(cheese:4268): cheese-CRITICAL **: cheese_camera_device_get_device_node: assertion 'CHEESE_IS_CAMERA_DEVICE (device)' failed

** (cheese:4268): CRITICAL **: cheese_preferences_dialog_setup_resolutions_for_device: assertion 'device != NULL' failed

I also tried:

sudo apt-get install cheese build-essential linux-headers-`uname -r`
[sudo] password for kangnahua:

build-essential is already the newest version.
cheese is already the newest version.
linux-headers-3.19.0-58-generic is already the newest version.
The following packages were automatically installed and are no longer   required:
libntdb1 python-appindicator python-ntdb
Use 'apt-get autoremove' to remove them.
0     upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

So cheese is the newest and the problem isn't cheese itself. Below is my lsmod:

  • Looks like an known problem: bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1433906. My suggestion would be to get Ubuntu 16.04 LTS (released on the 21st of April), boot from it an see if your webcam is recognized, if yes upgrade you 14.04 to 16.04. – koni_raid Apr 18 '16 at 21:55
  • This issue is now fixed in Xenial / Yakkety -proposed kernel, if the verification task went well, it should be available in updates about two weeks later. – P.-H. Lin Dec 23 '16 at 7:24

Looks like an known problem: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1433906. My suggestion would be to get Ubuntu 16.04 LTS burn it onto a DVD/USB-Stick (released on the 21st of April), boot from it and see if your webcam is recognized/working, if yes upgrade your installed Ubuntu 14.04 to 16.04.
