I just installed natty from scratch. If I use the nvidia-current driver, I cannot login. The unity bar loads on the left, but the status area never comes up and the UI never becomes responsive.

If I downgrade to nvidia-173, I am able to log in. The only problem I seem to have with nvidia-173 is that if I switch to the tty (ctrl+alt+f1) and switch back, the graphics are horribly corrupted. The applications re-draw but the backgroud is permanently corrupted.

Any ideas on the issue?

Maybe this could be helpful for solving your problem:

It is a similiar problem like mentioned here (with a workaround): Geforce Go 7300/7400 blacklisted, can I still run Unity? Geforce Go 7300/7400 blacklisted, can I still run Unity?
