I just installed Ubuntu, I've been a longtime Debian user but I'm a bit lost with some things.

My admin account has everything working nicely, I created a standard user account for my wife but I haven't been able to make the webcam work on her account.

I was thinking it had to be something related to the groups, when I ran groups on the admin account I got this: ale adm cdrom sudo dip plugdev lpadmin sambashare

Groups for my wife account: valentina nopasswdlogin

I was kind of expecting my account to have the usual groups (video, audio, etc), but got lost with this info. Any suggestions?

Help in advance.


Nopasswdlogin breaks a lot of things.

Don't use it for GUI login.

Use the built-in auto-login functionality instead(nopasswdlogin is supposed to be reserved for command-line users and is intentionally broken for GUI users).

  • I changed the my wife's user like you suggested but with no luck. After that I added her to the video group like @Thomas suggested in the answer below and no luck either. Any other suggestions? Thank you for such a quick answer. – user1294431 Jun 10 '12 at 22:25
  • Are you sure you removed her from the nopasswdlogin group and restarted and didn't just turn on autologin? – RobotHumans Jun 10 '12 at 22:29
  • Yes. From what I understand regarding groups there's no reboot needed, just to log out and back in. I rebooted anyway and nothing. valentina@piemur:~$ groups valentina video – user1294431 Jun 10 '12 at 23:37
  • I'll dig in to it in a VM for a bit tonight. I expect to update the answer or comment 'no dice' tomorrow. – RobotHumans Jun 10 '12 at 23:39

Your are right - this is a question of groups. You need to have the group video to use the webcam.

  • in a case where I tested this, being in appropriate groups didn't fix some issues (automounting for example). that's why i recommended not using nopasswdlogin instead of adding video...to stave off future questions. – RobotHumans Jun 10 '12 at 9:20
  • My webcam has these rights: crw-rw----+ 1 root video 81, 0 Jun 9 13:16 /dev/video0. So from my understanding you have to have the video group to use is. Of course you are right - nopasswdlogin breaks several tings. – Thomas Jun 10 '12 at 18:17
  • Thank you for your answer @Thomas, unfortunately neither adding the group or not using nopasswdlogin helped. If you have any more suggestions I appreciate it. Thank you again. – user1294431 Jun 10 '12 at 22:58
