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)

    Have you already installed the proprietary driver through "Additional drivers"? If yes please press Ctrl-Alt-t, in the terminal type: xrandr. Edit your question and post xrandr output. – phipsalabim Feb 19 '13 at 19:32

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

  • The following packets contain non satisfied dependencies: nvidia-current Impossible to correct issues, the failing packets are in state "keep in state" – Vincent Feb 19 '13 at 20:22
  • Aucun probleme mon ami. On s'entend bien. I updated my answer, as Luis Alvarado pointed out a better repository and a more recent driver. Just repeat the 3 steps in my answer again. – phipsalabim Feb 19 '13 at 20:27
  • Thanks a lot phipsalabim and Luis, the installation of nvidia-313 went fine (I think), after reboot, the driver is stated as activated but not in use inside the "Proprietary drivers" panel; how can I force the use of this driver ? – Vincent Feb 19 '13 at 20:40
  • if it says activated it means it's being used. Everything is fine. Just confusing semantics. Is the resolution ok now? – phipsalabim Feb 19 '13 at 20:41
  • No, that's why I mentioned the "not in use" statement, still cannot change the resolution and still not automatically detected – Vincent Feb 19 '13 at 20:46

  • "Aucun pilote propriétaire n'est utilisé sur ce système" – Vincent Feb 19 '13 at 20:54
  • Thanks, after using those following commands, the 1680x1050 resolution is automatically detected. Still no proprietary driver in use, but it satisfies my needs for the moment. Thanks a lot for your support –  Feb 19 '13 at 21:06

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.
