After installing ubuntu initially, upon startup it loads the nv driver and while trying to display I get nothing but artifacts and everything hangs. I have the restricted drivers installed and it works fine but due to incompatibility issues I would like to switch to a default driver like nv. I have a GeForce 7800 GT. The system recognizes it as such but it appears there's a bad interaction between nv and my 7800. The logs don't show anything wrong either. I'm not concerned with GLX support or anything fancy I just want to be able to display at 1440x900. Anything would help. Thanks.
