Screen Resolution Problem After Running Driver
 

I updated Mint 5 just now, then tried running compiz fusion, this configuration never did it before, and I opted as in the pop up to run the 3 D graphics card, after which, everything looks too big. That is after a restart. Opting to adjust resolution could only make things blockier. I had this problem before, but was lucky that as I used a program and picked some options it asked if it could undo something modified and after selecting yes, it was alright again.

I look for a solution.

Using an old NVIDIA card. How can I change the alteration?
