Title:
  Blackscreen detected in-built camera

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I got an Acer with a Suyin built-in camera. It has worked perfectly
  since I have change from Window 8 three weeks ago but recently has
  showed me a black screen when using Skype or cheese. I have tried to
  reboot Ubuntu on it. First time it did work until I installed the
  recommended updates. Untill third time I rebooted, it has worked but
  somehow it went black again after some updates. I now tried to boot
  Ubuntu version 12.04 instead of 12.10. It has work so far with all the
  updates installed I could get a picture on my webcam when using Skype.
  But today without any updates it crashed and now I am back with the
  black screen on both Skype and Cheese.

   One other thing is my screenlight cannot be dimmed, this is from both
  Ubuntu version. When I pressed the command «Fn+up or down» it doens't
  dim the screen but it shows the screenlight bar going up or down on
  the screen. So I know it is working somehow if it shows the command on
  the screen.

  Here I have tested and got some information from the system to
  understand better what was going on with the camera. Unfortunately I
  dont really understand them. Hope you can do better :)

  
  The camera has been detected by the System Testing but gives me anwers like this for the first test: *Could not load image 'camera_test_25112w.jpg'.Error interpreting JPEG image file (Improper call to JPEG library in state 200)*

  And the final results: camera/detect PASSED: /dev/video0: OK name : HD
