Looks like it isn't finding the kernel nvidia driver. Guess when you upgraded it updated the kernel but for whatever reason didn't rebuild the nvidia driver. Probably if you go into grub and boot an earlier kernel it'd work.
Try `sudo apt-get purge nvidia-*` and then reinstalling nvidia-current via jockey. That should force it to rebuild against the current kernel. It would be interesting to see a make.log or something to see why the kernel module didn't get built. Have you manually installed kernels during this timeframe? ** Description changed: Upgraded to 12.04 beta about a week ago, display worked fine. Performed an apt-get upgrade yesterday and now the nVidia driver won't load anymore (both available versions in Jockey). Xorg tries to determine the monitor on startup but fails (see attached screenshot).
