I faced the same issue, i.e. no unity. I was about to resolve the issue by installing linux headers and source and reinstalling the nvidia-current package again, and it was to compile successfully. But even after that unity didn't show up, so I followed the instructions here (http://askubuntu.com/questions/285779/after-upgrading-to-13-04-unity-interface-is-not-showing) and unity is working fine now. Still this is a major bug and must be resolved!
