Public bug reported:
The following bug affects both Cheese and Skype, but not guvcview.
I had an intermittent problem of the video feed from the webcam failing,
apparently after waking from sleep. When I opened Cheese or the video in
Skype I would see just black. When this happened the light on the camera
would not come on. However the video feed to guvcview continued to work
fine and the light would come on in that case. I noticed that this
problem became a lot less frequent when I switched from Unity to XFCE,
as did another problem of networking failing on waking from sleep, so I
suspect there may be a connection between these two problems.
What used to happen was that I would either reboot or simply log out and
log back into my gui session and the video from the camera would be
restored. However when the problem reoccurred yesterday nothing I did
would bring the video back to Cheese and Skype, not even rebooting,
running Cheese as root or starting a gui session as a different user.
This means that video to Cheese and, much more importantly, to Skype is
now permanently disabled. The one thing I noticed as being odd which
might possibly have contributed to this situation is that when I logged
out of my gui session and tried to log back in again, the gui failed to
launch and I ended up having to reboot.
To summarise:
- Webcam video to certain applications, including Cheese and Skype, sometimes
fails.
- At least one application, namely guvcview, is not affected.
- The failure is sometimes capable of persisting through several boot cycles.
Needless to say, not being able to do video chat is a very serious bug
and a very good reason for a user to look for another operating system.
