It was firstly found when using stock 12.04.3 image, during on installing step of "Choose a Picture", the webcam view only playback with green screen, but it still can capture correctly if you hit the button. After completely installed 12.04.3 system or upgrade your X driver stack to lts-raring, on system with haswell chipset, webcam capture will playback with green screen. To reproduced this problem we could use: guvcview luvcview mplayer tv:///dev/video0 -vo xv vlc v4l2:/ //dev/video0 -V xv On the same hardware system, To validate that webcam works fine with other output drivers: luvcview -w mplayer tv:///dev/video0 -vo x11 vlc v4l2:/ //dev/video0 -V glx By downgrade to xserver-xorg-lts-quantal also fixes this issue, its also verified on 12.04.2 stock image with the same webcam.
