You have been subscribed to a public bug: If you have a MS HD Webcam (cinema/studio) connected during boot, the startup time considerably slows down and halts in a low-graphics mode error with a complete system freeze.
This error occurs *after* a properitary graphic driver was installed (tested with AMD and Nvidia). With a disconnected webcam the system boots without a problem. This bug *does not occure on* non-debian based distributions like arch- linux. Workaround: Quickly open a console during boot and restart lightdm.
