I just installed 12.04.2 and I'm stuck with 1024x768 resolution on my GTX560. Impossible to change the resolution; the native resolution (1680x1050) is not detected. Any clue ? Thanks.

The additional drivers panel doesn't show any driver to install, so I kept the original driver.
Here is the xrandr output anyway: 

Screen 0: minimum 8 x 8, current 1024 x 768, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DVI-I-2 connected 1024x768+0+0 (normal left inverted right x axis y axis) 430mm x 270mm
   1024x768       75.0*+   60.0  
   800x600        75.0     60.3  
   640x480        75.0     59.9  
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-I-3 disconnected (normal left inverted right x axis y axis)

Ok. We should install the driver first. In the terminal run:

sudo add-apt-repository ppa:xorg-edgers/ppa

enter your password (you won't see anything as you type it, don't worry) and confirm adding the repository. It contains the latest drivers.

update repos

sudo apt-get update

Now let's install the driver, still in the term

sudo apt-get install nvidia-313 nvidia-settings

You will have to reboot. Report back

Driver activated but not in use problem

Never seen that before. Please try:

sudo apt-get --purge remove xserver-xorg-video-nouveau

then 

sudo nvidia-xconfig

logout and login again

I have the same Nvidia card model so here are the links that will get you through several possible problems you might get on 12.04 related to that card:

HDMI/VGA connection cuts borders of screen or creates blurry text
(This is just in case you get the top/bottom parts of the screen cut out)

Enable HDMI audio for an Nvidia card
(This is so you know about the HDMI Audio)

How do I install the Nvidia drivers?
(RECOMMENDED LINK - Recommended way of installing the drivers for you. This will also fix other problems you might encounter with a high end video card like the one you and I have.)

Difference between Additional Drivers (Nvidia)
(So you know the difference between all of drivers found in Ubuntu related to this card. I would again recommend using the above link to install the latest driver)

Why does Nvidia Settings have different resolutions than the Monitor option?
(Reasons why the resolution can be different that what is advertised when using a PC and a TV Monitor)

In your case, use the nvidia-313 driver found in the Xorg Edgers PPA which I mention in the link I recommend above.
