Vincas Dargis, to see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

You can start Cheese again and it might start video, but sometimes not, randomly. In case when there is no image, opening Settings and changing resolution makes video appear! Tried to downgrade libv4l-0, libv4lconvert0 to 14.04 version (1.0.1 I believe) but it did not helped. Upgrading to Linux 4.8 (from hwe package) did not helped either. On other laptop with Ubuntu 14.04 (with same 4.4 kernel from hwe package) there is no issues as such, so I assume it's bug with Cheese itself. Interestingly, on yet other laptop (Asus N551JM) with Kubuntu 16.04 Cheese does not show video on launch always (tested with many restarts of Cheese app). If I change resolution in Settings, it does start to show video thought. That computer is faster than Dell 6400 one, so I'm guessing it could be some kind race condition..? I cannot reproduce this issue with Camorama for example, it seems it always starts video successfully for this webcam. - ProblemType: Bug - DistroRelease: Ubuntu 16.04 - Package: cheese 3.18.1-2ubuntu3 - ProcVersionSignature: Ubuntu 4.4.0-53.74-generic 4.4.30 - Uname: Linux 4.4.0-53-generic x86_64 - ApportVersion: 2.20.1-0ubuntu2.4 - Architecture: amd64 - Date: Sat Dec 17 21:15:27 2016 - InstallationDate: Installed on 2015-06-25 (541 days ago) - InstallationMedia: Kubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150219.1) - MachineType: ASUSTeK COMPUTER INC.
