Hello!

It seems like ubuntu can not recognize my GPU. -> Details -> Graphics: Unknown.

The system it self eats battery, with poor performance in games etc.

What do I need to do?

Regards

What are your hardware specs? Did you try running the additional drivers utility?

Yes. When running the additional drivers utility it won't find any results.

You need to install Bumblebee and related packages for your NVidia graphics to work. Do NOT attempt to install a package from NVidia site, because those are made for single graphics solutions, which is not the case here.
It's easily achievable from terminal using following commands:
sudo add-apt-repository ppa:bumblebee/stable
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia nvidia-current

After those, you need to reboot.
To run graphics heavy applications, you must use the following command:

optirun [options] <application> [application-parameters]
or else onboard Intel graphics will be used instead of NVidia one.

To access NVidia chip settings, use the following command:
optirun nvidia-settings -c :8
