build-in webcam issue: how to turn it off during boot-up?

Hi,

I have a laptop - Asus K52J & x86_64 - with a built-in webcam. During boot-up, the webcam turns on in - rough guess - 50% of the time. I don't find any obvious pattern when/why the webcam turns on.

Searching this forum/internet doesn't give me a good answer...

1/ I prefer a solution where the webcam is turned off on boot and where I can turn it on when necessary.
2/ I can afford to disable the webcam when running linux.
3/ Disabling in BIOS (often given solution) is not an option.

For 1/, the only solution I got was running following and closing mplayer window. This turns off the webcam, but this is not an efficient manner. Is there another software-based work-around?

mplayer tv:// -tv driver=v4l2:device=/dev/video0

For 2/ I hear blacklisting the module is the solution. But how do I find the correct module?

lsmod

gives a whole list (pastebin).
Is it videodev and/or v4l2_compat_ioctl32? How can I be sure? Any advice on this for other users with other laptops?

Thanks for any help on advance!

Kind regards,

Your webcam uses the uvcvideo module so blacklist that one in /etc/rc.conf.
