Re-install old nVidia driver?

[skootles]

Okay, so, I've installed Kubuntu 7.04 over Ubuntu, and I chose to install the nVidia driver when I launched the installer. Now, I can't get my resolution past 640x480. Is there any way I can get it working higher than that? If not, how do I get the previous drivers back?

I blogged about this here.

It's a little long but I had the same issue.
