Critical Error in GPU

user@name:~$ nvidia-settings

(nvidia-settings:1333): GLib-GObject-CRITICAL **: 13:23:54.137: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

Secure boot is disabled (Other OS selected) In system info it see my Nvidia GPU, but cant see cli programs. Also i installed with opencl-icd command which i found in this forum.

That error is normal when running nvidia-settings, just ignore.

Ok but also i have another problem. I cant see my GPU in openCL

Please run as root and attach the resulting nvidia-bug-report.log.gz file to your post.

I dont know where it is. Is it might be the problem before installing nvidia i removed by purge nvidia, and in clinfo i cant see the cuda. In forum i realize someone solved the issue with installing cuda. Also cuda installition installing some dependencies too. Which i autoremove after removing cuda.

Which distro are you running? is installed alinside the driver, so if it’s not there, there’s likely no driver installed.

Oh! Yeah, there it is. Im using Debian.
nvidia-bug-report.log.gz (326.3 KB)

Nvidia driver is installed and working fine, so should be an opencl issue.
Please post the output of

With/Without sudo:
Number of platforms 0

ICD loader properties
ICD loader Name OpenCL ICD Loader
ICD loader Vendor OCL Icd free software
ICD loader Version 2.3.1
ICD loader Profile OpenCL 3.0

I might did a few changes in /etc/OpenCL/vendors
And when i type nvidia-settings its giving me the error of cant opening directory and in X11 making another conf file

Looks like the nvidia icd is missing. Please make sure the package nvidia-opencl-icd is installed.
Please post the output of
dpkg -l

nvidia-opencl-icd is installed. What grep command should i use ? The output is 1500 row

Sorry, I meant
dpkg -l |grep nvidia

Does the file /etc/OpenCL/vendors/nvidia.icd exist? If not, please reinstall `nvidia-opencl-common

Yes it is exist and this is the output when i cat >
But also in /etc/OpenCL/vendors there was another file pocl.icd
That was what i mentioned before. I changed its name and made a backupICD file and put it in there. Nvidia should be the main/applied one in the vendors right ?
But also i guess some nvidia configuration files in /etc/X11/xorg.conf directory. When i launch nvidia-xconfig its giving me some errors about cant write the file, and rewriting again. And maybe its all about like i said in first installition i purge removed nvidia, then i reinstalled the cuda.

If it will be just fine and fresh installition, i can do it. Pls just type down the correct commands to delete/remove them all with no doubt and safely. And install with the pure correction.

Thanks for your time

You should rather remove the file or uninstall the package it belongs to and not rename it in its directory.
Anything in /etc/xorg.conf is only writeable by root so the error you’re getting from nvidia-settings when run as user is expected. Furthermore, you shouldn’t mess around with that anyway, it also has zero influence on OpenCL.

I saw it in a forum before there, that was a solution for him. Like you said, i deleted the file. It was cuda’s i didnt install about it

I run sudo nvidia-xconf and it write the file but not in the /etc/xorg.conf it created /etc/X11/
And there is xorg.conf & xorg.conf.backup (nvidia-xconf created them) & xorg.conf.nvidia-xconfig-original
And also there is xorg.conf.d directory and inside there is another xorg.conf file. Maybe something is crossing.

xorg.conf has nothing to do with opencl. Don’t fiddle with it.

Ok whats next then ? When i try to use my GPU from CLi this error occurs:

cuInit(): unknown error


ATTENTION! No OpenCL, HIP or CUDA compatible platform found.

You are probably missing the OpenCL, CUDA or HIP runtime installation.

  • AMD GPUs on Linux require this driver:
    “AMDGPU” (21.50 or later) and “ROCm” (5.0 or later)
  • Intel CPUs require this runtime:
    “OpenCL Runtime for Intel Core and Intel Xeon Processors” (16.1.1 or later)
  • NVIDIA GPUs require this runtime and/or driver (both):
    “NVIDIA Driver” (440.64 or later)
    “CUDA Toolkit” (9.0 or later)

Now im really close to the solution. My nvcc version and nvidia version is not match. Yes, that common issue. But i didnt solve it. How can i solve it ?
