I ran into the same problem, and checked out the permissions on /dev/video0:
crw-rw----+ 1 root video 81, 0 Aug 22 11:14 /dev/video0 I also ran $(groups) to check my group membership and found that I wasn't in the group video. To rectify this, I ran $(sudo usermod -a -G video `whoami`), and after logging out and back in, I could use cheese normally again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1445039 Title: Device '/dev/video0' is busy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cheese/+bug/1445039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
