I've installed 3.19.0-031900-generic. The regression is fixed, partly. VLC, Chrome and Firefox are able to use it again by their default settings. guvcview is not, the preview image is still lacking, however the warnings have changed, no more 'device busy', but several warnings instead: control id: 0x009a0901 failed to get value (error -1) control id: 0x009a0902 failed to get value (error -1) control id: 0x009a0903 failed to get value (error -1) control id: 0x009a0908 failed to get value (error -1) control id: 0x009a0909 failed to get value (error -1) control id: 0x009a090d failed to get value (error -1) guvcview was working well with 3.2 too. However, this may be an compatibility problem that is caused by guvcview's implementation details. If this is clarified, we nay tag 'kernel-fixed-upstream'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1422680 Title: v4l2 regression: T420s built in camera stopped working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1422680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
