USB Webcam partly working in Linux Mint 8


Hey all.

A bit strange problem:

A linux Mint 8 (32 bit edition) (Ubuntu Karmic based)with a USB Webcam installed.

The default user has both video (cheese) and mic working flawlessly.
(Just did install the usual webcam software).

There are 3 other users on that PC.

The mic is working too for them, but no camera?!

All users is in both the audio and video groups. It is checked using sudo adduser ................

It might be a setup problem for the 3 users, but I don't know how.

Otherwise????

Please help.

Best regards

Stardustdk

hi

if its groups....the only thing I can see is one (or is it all?) users are member of adm group= admin
allegedly this allows only reading of logs but maybe on your system it overrides a file or device permission?

lets try to eliminate file permissions?

find the name of the executable for the software....and show......ls -al executablename
find the names of the devices of the webcam....mine may differ suggest ls -al /dev/video0 and /dev/v4l/*

maybe even tho they are members of video.....the device is root permission only?
