Can't detect webcam depending on user

Asked by Francesc Vilches

I have 2 users created in Ubuntu 7.04

With first one I can access webcam (logitech Quickcam pro 4000) using ekiga (the user I used to install the operating system).

The second user is not able to see the installed webcam....... .-(

Am I doing something wrong?

Check which group has access to /dev/video0

do ls -l /dev/video0

which will display something like :

crw-rw---- 1 root video 81, 0 2007-08-10 16:20 /dev/video0

this means user is root and group is video.

Make sure user who cannot see webcam is put into the group.

Not sure but you may need to logout as that user and then login again.

Hope that helps

I did:
groups merce

and I realised that my wife's user wasn't in video group.

so I had a look at man manual and I did:

sudo adduser merce video

Now works fine (without restarting X session).

Apologies..........just beginning to learn gnu/linux systems. ;-)
