Webcam availability

Post by zl1bjq » Tue Jan 16, 2018 6:32 pm

My webcam video stopped working in both Cheese and Skype.
It seemed something was grabbing the webcam at boot up since the webcam blue light stayed on. I didn't like that and neither Cheese nor Skype could access the video. (The mic was OK)
So I stopped it booting by opening the editor
gksu gedit /etc/modprobe.d/blacklist.conf
Then adding
blacklist uvcvideo
at the bottom, then save it and exit.

Now after boot the webcam is dead.
To restore the webcam and make it available to either Cheese or Skype I open a Terminal and type
sudo modprobe uvcvideo

When that is done Cheese and Skype (restart Skype) both work perfectly.

So now - how do I automate that sudo modprobe uvcvideo to run after boot but before Skype starts?
I guess I could stop Skype opening at boot but that wouldn't fix the webcam problem.
(If you see what I mean!)

Alternatively what is running the webcam at start up and how to stop it.?

You can try adding modprobe uvcvideo, without sudo, to the file /etc/rc.local, before the line that reads exit 0. Check the execution bit is set on that file too.
There are no silly questions, but there are silly answers.
