This seems very common topic these days but i have some additional problems. The additional drivers option is greyed out, and it says there are no drivers being used. The graphics driver shows "unknown" in the system settings and i cant configure multiple monitors as it wont detect displays at all. I have the latest driver from Nvidia 295.40 installed. I also tried to manually start X server by sudo service lightdm start and contrary to the config settings it says its already running

I have an dell XPS with Nvidia GeForce GT 420M. Thanks in advance

I used Ironhide driver using the approach here:- http://community.linuxmint.com/tutorial/view/610

It worked fine in Ubuntu 11.10 although I have a few problems in 12.04. The graphics works fine but I get error messages. I have an Acer Aspire with the same graphics card as you. This runs compiz, gives Unity 3D etc but is not perfect. The Nvidia drivers do not work in Ubuntu although that may change.

Good luck
