Comment 75 for bug 1310023

sorry for chiming in here. I am on Mint 17 and experiencing these issues with my GTX 850m

I have tried as much as I can from this thread,
and now am faced with "

ERROR: nvidia-settings could not find the registry key file. This file should
       have been installed along with this driver at
       /usr/share/nvidia/nvidia-application-profiles-key-documentation. The
       application profiles will continue to work, but values cannot be
       preopulated or validated, and will not be listed in the help text.
       Please see the README for possible values and descriptions.
