There is more annoying to tell about this: I also upgraded from natty to oneiric. My system with nvidia-current (280.13) even won't login, if i use lightdm.
During the installation process, i had been asked which manager to use. I'd chosen lightdm. That left me with an unusable system, because the xserver went into an infinite loop. Only if i switch to use gdm (dpkg- reconfigure lightdm), xserver starts.
