I've just done a fresh install on a new laptop that has a 670M. Ubuntu defaults to using Nouveau however there's a fair amount of corruption on certain visual elements.
For reference, Windows 7 & 8 don't encounter the same issues.
So, I figured I'd try installing the latest nvidia drivers, although after installing them, my resolution becomes extremely low and Unity appears to fail to start (although Nautilus seems fine and I get a "desktop", just nothing else).
What's the best way to get working nvidia drivers on 12.10 with a 670M?
