Graphics Drivers issue

Issue Symptom

nvidia-settings

ERROR: NVIDIA driver is not loaded

(nvidia-settings:4676): GLib-GObject-CRITICAL **: 14:26:43.940: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

** (nvidia-settings:4676): CRITICAL **: 14:26:43.943: ctk_powermode_new: assertion '(ctrl_target != NULL) && (ctrl_target->h != NULL)' failed

ERROR: nvidia-settings could not find the registry key file or the X server is
not accessible. 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.
