EDIT
After trying a lot of things I gave up and I installed Ubuntu 14.04. Now I can simply install the proprietary drivers selecting them in the Additional drivers settings.
I'm trying to install the nvidia drivers for my notebook but I'm having a lot of troubles...
First some info on my system. I have Ubuntu 12.04 64 bit, lspci gives:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M / GT 620M/625M/630M/720M] (rev a1)
the kernel is 3.5.0-54-generic.
I have installed the nvidia-current package but then I ended with a screen resolution of 640x480. So I purged nvidia stuff, I removed the /etc/X11/xorg.conf file and I got back my system using the nouveau driver.
How can I install the nvidia drivers?
In my repos there are other packages
$ sudo apt-get install nvidia-
nvidia-173 nvidia-331-updates-uvm nvidia-current-updates-dev
nvidia-173-dev nvidia-331-uvm nvidia-experimental-304

nvidia-331-dev nvidia-current nvidia-settings-experimental-304
nvidia-331-updates nvidia-current-dev nvidia-settings-experimental-310
nvidia-331-updates-dev nvidia-current-updates nvidia-settings-updates
but I don't know which else I can try...
If I understood correctly my pc has the optimus technology that is it has two graphics cards, one Intel and the other is the Nvidia one. Some comments on forums seem to suggest that this technology is supported in Ubuntu less than 13 only installing bumblebee, is that correct?
If I upgrade my system to Ubuntu 14.04 the problem remains the same?
