I'm trying to troubleshoot something; nvidia-settings is showing me this error: Code: 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-340.65-key-documentation or /usr/share/nvidia/nvidia-application-profiles-key-documentation The application profiles will continue to work, but values cannot be populated or validated, and will not be listed in the help text. Please see the README for possible values and descriptions. Not only do I not have the indicated missing file, but I don't even have the directory. If you do, please post the contents of either of the two files above so I can take a look at them?

Thanks for that, D. Just before I found your post, I figured out a workaround. nvidia-drivers does not create the directory or its contents if the 'tools' use flag isn't enabled. This flag also creates a driver-dependent version of nvidia-settings. I disabled this flag a long time ago for xfce4-sensors-plugin, which requires nvidia-settings and compiles against it; there is a standalone package for that purpose in portage, which I have run all along. The plugin can't/doesn't work with the driver-dependent version. So my problem is these new error messages are happening now. So I figured out that if I compile the driver with the tools flag enabled, generating the directory and its contents, and then recompile the driver without the flag, and keep the directories intact, everything works as it should. It's a kludge, but I filed a bug so the devs can check it out.
