Well, that certainly is a difference. The nvidia package includes the file
`/usr/lib/modprobe.d/nvidia.conf` that contains the line `blacklist
nouveau`. That's necessary because if the nouveau driver is loaded first,
then the nvidia one cannot work properly.
But you are not loading X, so I'm guessing that your nvidia driver is not
being loaded either (the kernel driver is probed by the X driver IIRC), so
you are running with the default vesa console.
You can try running `modprobe nvidia` and see if it makes a difference. If
that's not the case, reboot and run `modprobe nouveau`.
Or maybe I'm wrong and the nvidia driver is being loaded automatically. If
that's true, you can try blacklisting it and modprobing nouveau.
