Webcam troubles

hi,
I bought a new lenovo sl500. I'm currently installing the latest release of arch linux. till now, everything seems to work fine. suspend, wifi,.. works out of the box.
however, I some troubles with the webcam. I made a lsmod and saw that the module uvcvideo gets automatically loaded. ok. but I have no /dev/video device. so cheese and skype complain that there is no webcam available.
however, the led of the webcam is on.
any ideas what I can try?

Re: Webcam troubles

hi
thank you for answer. unfortunately, it didn't help. But I want to correct myself, because I have a dev/video device. however, cheese and skype still are of the opinion that there is no webcam available.

Re: Webcam troubles

Ok, next try:
Please install guvcview (a program similar to cheese) from AUR
http://aur.archlinux.org/packages.php?ID=16521
and start it from a terminal window using "guvcview". Check if it works and, if not, look at the messages it throws at you. If you see something about "select timeout" and "resource temporarily unavailable" then you just hit a bug in the uvcvideo driver present in kernel version 2.6.30. It is said to be fixed in upcoming 2.6.31 release but I didn't check that.

Re: Webcam troubles

Hi,
thank you now it works. but I'm really ashamed, because it was working all the time. but I had to start cheese with root permissions. I saw the permission denied message when I started guvcview the first time as normal user. I adjusted the permissions and now it works.
many thanks.
