Maybe it's beginner's luck, but I had, seemingly, the exact same problem on a Dell Inspiron 1525 with the integrated webcam. After hours of research, I decided switch to try to deactivate compiz and guess what? It works! So here is step by step what I did:
1- System-->Preferences --> Appearance --> Effects --> "None" (to deactivate compiz) 2- Open Cheese and try any other webcam app. (I still have problems with Skype) 3- Jump and shout your joy (hopefully) 4- Reactivate Compiz (just select "Customized") 5- You can try again cheese to make sure it's still working, reboot and check again. It did it for me. Good luck -- cheese malfunctioning with UVCVIDEO webcams (was cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards) https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
