I install the driver but the system shows that the nvidia driver is not being used. I already tried a bunch of things like: purge and reinstall the driver, all the others avaiable drivers, even the .run download from the nvidia site, blacklist nouveau, ocl-icd-libopencl1, bumblebee and probably some others i can’t even remember now. All of this were done isolated and in combination with each other, by undoing the modificatons i had done or by formating and starting all from scratch.
I don’t thing the problem is a hardware one because everything works fine on windows.
Here are some information:

NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I folloed this instructions: " Please always include a copy of an
nvidia-bug-report.log.gz file, which can be generated with the
nvidia-bug-report.sh script shipped with the NVIDIA Linux/FreeBSD graphics drivers and installed in your PATH; the log file will be placed in the current working directory. Attach the log file by clicking the Upload button in the post composition window."
But received this message: “Sorry, the file you are trying to upload is not authorized (authorized extensions: jpg, jpeg, png, gif, log).”
So i removed the .gz from the file nvidia-bug-report.log.gz
