Guys,
I am using backbox as main OS since many months now...and I have never used the web-cam so far, only few times in Ubuntu 12.10, the native OS of my laptop, and it was ok.
But, in backbox, no way, does not work and does not even find any camera...do you have any tip to fix this ? i have been looking in other forums but all solutions point to Ubuntu issues, and do not apply to me.
My laptop is a Gazelle professional from System76.

Tx

Hi,

When you have problem like this you need to see what is your camera model with lsusb from terminal, then search Google to see how to run your camera model with ubuntu 12.04. If you can't find solution give us lsusb message and we will check that for you.

Cheers !

ZEROF,
i have been checking around this issue...i think it is not related to bbx rather a problem with built-in web-camera itself...

Look:

Code: [Select]
:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 003 Device 002: ID 046d:c016 Logitech, Inc. Optical Wheel Mouse
Bus 001 Device 003: ID 07ab:fc86 Freecom Technologies

then, if i run cheese:

Code: [Select]
** (cheese:4814): WARNING **: cheese-window.vala:1624: Error: Nessun dispositivo trovato

then gstreamer results:

Code: [Select]
gstreamer-properties

then i did try to use the camera through vlc just as additional test :
Code: [Select]
vlc v4l2:///dev/video0
VLC media player 2.0.5 Twoflower (revision 2.0.5-0-g1661b7d)

[0x7fa468000b78] main input error: open of `v4l2:///dev/video0' failed

Interesting it is the prior few updates the webcam was working. After few updates (in both main OS, native 12.10 and in bbx) no longer works.

Any clue ?

Tx again

Hi,

You right, after updates Ubuntu removed some plugins from system, and now many users have problem like you. Try to install all of this plugins :

gstreamer-properties-Message: Skipping unavailable plugin 'artsdsink'
gstreamer-properties-Message: Skipping unavailable plugin 'esdsink'
gstreamer-properties-Message: Skipping unavailable plugin 'sunaudiosink'
gstreamer-properties-Message: Skipping unavailable plugin 'glimagesink'
gstreamer-properties-Message: Skipping unavailable plugin 'sdlvideosink'
gstreamer-properties-Message: Skipping unavailable plugin 'v4lmjpegsrc'
gstreamer-properties-Message: Skipping unavailable plugin 'qcamsrc'
gstreamer-properties-Message: Skipping unavailable plugin 'v4lsrc'
gstreamer-properties-Message: Skipping unavailable plugin 'esdmon'
gstreamer-properties-Message: Skipping unavailable plugin 'sunaudiosrc'

This is not 1st time i see that Ubuntu remove plugins and that this make problem for end users. If this don't work try to install chees and gstreamer from source, because they make updates but they don't update packages in repositories. I know how you feel bro, but this is not only BBox issue.
