Ubuntu 14.04 nvidia GTX 960M drivers not working

Question

I know there are a ton of nvidia driver-related questions, but I tried everything I could find and none worked.

I am using an ASUS ROG GL752VW, core i7 6700HQ, nvidia GTX 960M 4GB GDDR5. I first installed Windows 10 and left ~200GB for my linux OS.

1. Created Ubuntu 14.04 Live-USB with rufus
2. Tried to boot from the live USB. Did not work, had to enable nomodeset from the advanced boot options, because it stuck at Starting CUPS printing spooler/server [ OK ] (solution from here.
3. After successfully installed, tried installing the drivers apt-get install nvidia-current
   • After reboot, stuck in a login loop (after inserting correct password, screen would go back to login)
   • Uninstalled the drivers apt-get remove --purge nvidia-*
4. Tried add-apt-repository ppa:graphics-drivers/ppa and installing the newer drivers (latest is 378)
   • Again, same thing happened
   • Uninstalled them once again
5. Tried this, this, this and this. Nothing worked, same issue.
6. Tried several different drivers (304, 170, 358, 367, 285 and more), with no result.

I also had a GTX 950M laptop and it was working perfectly with nvidia-367 driver.

Could it be a problem with the actual card? If so, has anyone managed to get it working on an UNIX system?

Thanks in advance.
