Bug Description

Switching from ubuntu 14.04 to ubuntu 16.04 I am having trouble using nvidia discrete graphics adapter when trying to switch b/w intel GPU and Nvidia GPU. When I switched back from ubuntu 16.04 to 14.04 and tried to upgrade the kernel from 3.19.0-80 to kernel versions 4.4.0-21 until 4.4.0-64 the graphics driver starts to malfunction and can't switch b/w the GPUs, while it works fine with kernel versions 3.19.0-x. Please look into the problem, and thanks in advance for your help.
