Running nvidia-settings currently gives the following error:
ERROR: nvidia-settings could not find the registry key file. This file should have been installed along with this driver at either /usr/share/nvidia/nvidia-application-profiles-340.17-key-documentation or
/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.
Seems like the file is missing in the package.
