I’ve installed the proprietary driver(video-nvidia) for my gtx 960m graphic card on manjaro(arch base) linux using
$ sudo mhwd -auto pci nonfree 0300
command.
In the booting screen under the /dev/nvme0n1p3: clean, .... blocks message, it says [FAILED] Failed to start Load Kernel Modules in a moment and the system boots up.
$ nvidia-settings
ERROR: NVIDIA driver is not loaded
(nvidia-settings:3503): GLib-GObject-CRITICAL **: 14:19:17.629: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** (nvidia-settings:3503): CRITICAL **: 14:19:17.631: ctk_powermode_new: assertion '(ctrl_target != NULL) && (ctrl_target->h != NULL)' failed
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
I also had nvidia-settings could not find the registry key file or the X server is not accessible error and fixed it by following this thread: [HowTo] Fix the ERROR: nvidia-settings could not find the registry key file or the X server is not accessible - Tutorials - Manjaro Linux Forum
here is the result of sudo nvidia-bug-report.sh
