Upgrade Nvidia driver to v381.22

[soullivaneuh]

This is the last current stable driver for Linux: http://www.geforce.com/drivers/results/118524

This add support for 10 series Nvidia graphic cards.

I don't know yet if it fix #5067, but in any case, it worth to update it.

Could this update be pushed on a new bugfix release?
