Thanks to your answers and this discussion. I ran into this problem yesterday.
Although I tried the instructions by @cjjefcoat on #57, it didn't give me back
my display as expected. Unity got screwed up and although I could see the
display, the rendering was not proper. The windows didn't have the title bar
and most keyboard functionality won't work. I didn't even have the task bar.
I went back to -112 version of the kernel but only found the same result. So I
reinstalled all NVIDIA drviers and uninstalled CUDA with no luck at all.
Finally I tried restarting Unity by following #14 here -
and it worked for me :D
Now I tried running everything on 116 kernel and it works. So in case unity
screws up for any of you after you reinstall the 116 kernel, try restarting
Unity and hope it works :D

4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and
16.04) by an insufficient compiler!
Status in gcc:
Status in linux package in Ubuntu:
Status in nvidia-graphics-drivers-384 package in Ubuntu:
Status in xorg package in Ubuntu:
Running fine with nvidia-384 until this kernel update came along.
When booted into the new kernel, got super low resolution and nvidia-
settings was missing most of its functionality - could not change
Rebooted into 4.4.0-112 kernel and all was well.
The root cause of the problem has been found to be installing the -116
kernel without a sufficiently updated version of gcc. In my case, my
system received the gcc update AFTER the kernel update.
Uninstalling the -116 kernel and reinstalling it with the updated
version of gcc solved the problem for me.
