I have following drivers and CUDA installed on my Ubuntu 22.04 system
user@user3:~$ whereis nvidia nvidia: /usr/lib/x86_64-linux-gnu/nvidia /usr/lib/nvidia /usr/share/nvidia /usr/src/nvidia-535.104.12/nvidia user@user3:~$ nvcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2023 NVIDIA Corporation Built on Tue_Aug_15_22:02:13_PDT_2023 Cuda compilation tools, release 12.2, V12.2.140 Build cuda_12.2.r12.2/compiler.33191640_0 user@user3:~$ lspci | grep -i nvidia 01:00.0 VGA compatible controller: NVIDIA Corporation TU117M [GeForce GTX 1650 Mobile / Max-Q] (rev a1) 01:00.1 Audio device: NVIDIA Corporation Device 10fa (rev a1) user@user3:~$ prime-select query nvidia
but I get following errors -
user@user3:~$ nvidia-settings ERROR: NVIDIA driver is not loaded (nvidia-settings:4518): GLib-GObject-CRITICAL **: 13:36:04.690: g_object_unref: assertion 'G_IS_OBJECT (object)' failed ** (nvidia-settings:4518): CRITICAL **: 13:36:04.692: 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. user@user3:~$ 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 have tried rebooting system multiple times but still have above errors. What could be the issue?
