I'm running Ubuntu 12.04.2 32bit and the webcam of my Sony VGN-FE21M [0x0ac8 0xc002] laptop gives green/garbled/black output when trying to use it in cheese, xawtv, vlc or skype. The suggested solutions in https://help.ubuntu.com/community/Webcam/Troubleshooting don't work.

The output in the terminal when running 'xawtv':
v4l2: ioctl(fildes = 5 "/dev/video0", request = VIDIOC_QBUF, struct v4l2_buffer *data = { index = 0, type = V4L2_BUF_TYPE_VIDEO_CAPTURE, bytesused = 9682, flags = V4L2_BUF_FLAG_QUEUED, field = V4L2_FIELD_NONE, timestamp = { 18637,563 seconds }, timecode = { type = 0, flags = 0, frames = 0, seconds = 0, minutes = 0, hours = 0 }, sequence = 0, memory = V4L2_MEMORY_MMAP, m.offset = 2882400000, length = 16777216, input = 0 }) failed, Ongeldig argument (22, EINVAL) because the frame buffer is already in use

The output in the terminal when running 'vlc v4l2:///dev/video0':
[0xb53ed7a8] v4l2 demux error: Failed to unlock (VIDIOC_QBUF)
