Question

peter@JAVIS:~$ nvidia-settings
** Message: PRIME: No offloading required. Abort
** Message: PRIME: is it supported? no

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
prepopulated or validated, and will not be listed in the help text.
Please see the README for possible values and descriptions.
