You should not have to mess with any of that.  I no longer have any
*buntu machines with nvidia cards, so I do not know the exact name of
the packages, but what is output if you run "dpkg-reconfigure
<nvidia-driver-package>"

It sounds like somehow you booted a kernel without which the nvidia
module was compiled for.  dkms should have handled that, but
apparently not - or more likely, the driver build failed without
notifying you.

What is the output when you simply try to "modprobe nvidia" from a shell?
