Xorg freeze

While booting ubuntu after the latest updates with the newest kernel a blank(black) screen appeared and everything froze. When booting into recovery mode and trying to startx via command line the xorg Nvidia driver did not recognize a valid display. When booting the one-time-older kernel, everything works fine.
