Hi,
I'm not a "great" troubleshooter, but I thought I would just mention this, as it was a simple fix for me, but the solution was*very* obscure and challenging for me to locate by just searching UbuntuForums and the web in general.
There seems to be a certain number of Nvidia GPU users who are having, what appear to be random, "GPU Lockups". After searching around,there are lots of suggestions regarding, nouveau vs. ubuntu-repo-proprietary vs. newest-nvidia-website-proprietary driver search being the cause of the lockups.
Similarly,there are a lot of opinions regarding the compositing function (thatis, turning off composting) of your window manager (compiz, marco, orother, depending on your window management environment) being the culprit and losing composting may fix your issues.
And,these may be the correct suggestions for many people. It was different for me though. First, here are some of my system details (Iam running the most current proprietary driver for my GTX 750 from the Nvidia website (NVIDIA-Linux-x86_64-384.59) ):

I ran through various ubuntu/proprietary drivers and various composite/non-composite modes, but could not stop these freezes/crashes. Incidentally, these crashes would freeze the window-manager, sometimes the mouse-cursor as well, sometimes the mouse would still move, sometimes not.
The system would still be running though, and could be ssh-ed into. On connecting via ssh, I learned that these lockups also caused the Xorg process to go to a constant 100% and, also, become "un-killable",which is super annoying. This problem also make the Lightdm service unstoppable, so there was no way to get back to the window manager without rebooting, which required a full-on "REISUB"reboot, also, suuuuper-annoying
So the fix for me was adding the "nogpumanager" boot parameter to my /etc/default/grub file, as per the below (always remembering,of course, to run...
...to get the system to incorporate the change into the system's next grub boot), like so:
Link to a sample of my /etc/default/grub file
Now this would lead me to believe that something is broken in the way the gpu-manager is interacting with Nvidia cards, at least mine and, at least on 16.04.2. As mentioned before, I don't really have the "chops" to say I know that for sure. Perhaps something for a more skilled user to check out though? At any rate, I hope this will be of use to someone in future.
Cheers,
P
