My desktop symptom was similar, and fix was similar to your verification and Myzhar’s tip:
prime-select nvidia
reboot
I have the same error.
nvidia-smi 515.65.01
nvcc --version 11.7
prime-select query nvidia
zed sdk 3.7.6
ubuntu 20.04
You can find the full solution here:
I tried this but still not working. prime-select query shows nvidia but the when i do $glxinfo | grep OpenGL, it still shows vendor string Intel
I solved the problem by doing this.
- create a file prime-run and copy the contents
#!/bin/bash
export __NV_PRIME_RENDER_OFFLOAD=1
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __VK_LAYER_NV_optimus=NVIDIA_only
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json
exec “$@”
- copy prime-run to /bin
sudo cp prime-run /bin
- make it executable
chmod +x prime-run
-
Now if you do
prime-run glxinfo | grep “OpenGL renderer”
it should show NVIDIA -
Reboot the computer
-
Now run
prime-run ZED_Depth_Viewer
It is working but every time I have to do prime-run. Is there any workaround? prime-select still shows nvidia
Can you test if this solution works for you?
I guess there is something that forces your PC to use Intel GPU, maybe a power manager or something similar.
This worked for me. Thanks!

I had met the same problem. The terminal information as below:
As above discussion, I had tried the follow commads in my notebook:
- sudo prime-select nvidia
- reboot
But the problem was not solved. The configure of my notebook is :
- ubuntu 20.04.6
- nvidia-520.56.06
- cuda-11.8
Can anyone give me some advises? Thanks!
Hi @zhoupan9109
this seems a different problem not concerning OpenGL.
Please open a new thread and add information about the ZED SDK version that you are using.
