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.
Fixes
