So the problem is still that no program can connect to my camera...

"The indicator-light" at my camera is blue - so the computer has registred that it is there...

Thank you so much actionparship for helping me :-)

what is the output of:

dpkg -l | grep -i v4l

Thanks

I have install the update and then restart the computer - but it is like the programs did know that :-)

For the first time I did actually get a picture on in guvcview
- very bad quality - I did only seen some shadows - I did not get the opportunity to fix the picture before the program crashed...

And there are still a problem with v4l2 and the device /dev/video0

Promise me that you don't laughing of my english - I do my very best... :-)

I have a picture on in guvcview - And Im trying to make it gut...

But right now I can only get shadows of my self - 4 - 5 half heads beside each other...

But this is a start and more than when I was beginning :-)

It is not very easy to get a better picture - I have try to make new settings...
but it only make the quality of the picture more bad :-)

So I think I still need the right driver to get my camera make the right fokus.... :-) ???

Not sure then, you have a bleeding edge libv4l-0 which may have helped. I suggest you run:

ubuntu-bug cheese

and report the issue. The bug guys may get you to remove the PPA and use the default libv4l-0 version in the official repos.

The camera works fine in guvcview now - I'm working on to make work in skype also...
I don't care that it not work with cheese - I only need to use it with skype...

I hope that I can give you "Problem solved" very soon....

What is the output of:

uname -a

Thanks

This is the output:

 3.2.0-32-generic-pae #51-Ubuntu SMP Wed Sep 26 21:54:23 UTC 2012 i686 i686 i386 GNU/Linu

I have searched the internet and It looks like many have trouble with make their webcamera works correctly in skype...
especially after upgrading to 12.04

I found this in many other discussion:
LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so /usr/bin/skype

I have change this in the file... but I still can't get a test-button on in the option of skype...
I did only get a black picture

Maybe it will work when I call someone - but I don't think so :-)
