Again, I'm not familiar with nvidia in ubuntu; but IIUC in RH/rpmfusion 
boxes the nvidia-derived drivers may not be correctly installed unless 
their installation happens *after* any nouveau activity.  Perhaps the 
converse also applies.  After that, the nvidia module for the 
appropriate kernel has to be built (usually automatically, but can take 
minutes) before it can be used.  *buntu too?
