Screen freeze/black screen after installing Nvidia drivers (16.04)

• Videocard: GTX 560


• NVIDIA drivers installed: nvidia-367 (recommended for my card).


• OS: Xubuntu 16.04

Problem description:
Video card works perfectly while using X.org drivers, but after installing Nvidia's, I get a black screen or a freeze on the "decrypt HDD" screen.

I have tried various fixes I've found on the site, from setting "nomodeset" to trying every single driver available to "update-initramfs -u" various times. Recovery mode also works; checked with "lspci -v" and it properly runs the driver.
