If, like me, your are booting with UEFI (because having a triple boot ubuntu-windows-mac or because UEFI is the most modern type of bootloader and successor of EFI :p), you have to sign the proprietary modules each time they are recompiled (or upgrade kernel version) so that they are allowed to be loaded in the kernel.
- Step one, create a self-signed certificate to sign nvidia driver:
sudo openssl req -new -x509 -newkey rsa:2048 -keyout UEFI.key -outform DER -out UEFI.der -nodes -days 36500 -subj "/CN=rambou_nvidia/"
- step two load and store certificate in a supplementary key database MOC
sudo mokutil --import UEFI.der
- step three reboot your system
At this step after reboot you will be prompted to select your certificate to import in in key database. If you have inserted a password at certificate creation you'll be prompted to insert it. If you are not prompted, you may have to enter the BIOS by using function keys at boot time.

Now we can install our nvidia driver, but first let us take a selfi... no seriously we need to take a selfi with our lovely linux installation because it can be fucked... just kidding :D, it will not!
-
Before we install we first need to uninstall previous drivers, probably nouveau.
sudo apt-get remove nvidia* && sudo apt-get autoremove
sudo nano /etc/modprobe.d/blacklist-nouveau.conf
and add lines below
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
disable the Kernel Nouveau by typing these lines in a terminal window:
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf
and after that
update-initramfs -u
Now you can reboot your computer, and when you get to the login prompt, press Ctrl+Alt+F1 to exit to the terminal console. Login with your username and password. stop your display manager or the X server, sudo service lightdm stop
- finall step install nvidia drivers
sh ./NVIDIA-Linux-x86-319.32.run -s --module-signing-secret-key=/path/to/UEFI.key --module-signing-public-key=/path/to/UEFI.der
