Can you help me in some way? thanks in advantage.
Hello Myzhar,
I’m having the same issue.
The is of course plugged in and the blue LED on the front turns on (and stays on until unplugged)
I can see the video when I open a camera app.
Running on Ubuntu 22.04, x86 platform
The output of prime-select is Usage: /usr/bin/prime-select nvidia|intel|on-demand|query
While prime-select query gives: on-demand
I also tried to force nvidia by running prime-select nvidia
but same result.
Please advise.
Thank you
sorry for being late on this, i followed the guideline you linked to me, but after running sudo prime-select nvidia it tells me : ‘Error: no integrated GPU detected.’
also let me append the nvidia-smi output.
@franzhd please verify the setting in the BIOS of the laptop.
You must be sure that the automatic GPU selection is disabled and the NVIDIA GPU is the default selection.
Hello, sorry for being late on the topic, i did update the nvidia driver to 530 and with cuda 12.1, but i still have the problem. It seems like a problem with usb stuff. Infact it gave me problem also inside the docker.
This is my console output for ZED_Diagnostics, nvidia-smi and nvcc.
I just noticed that it’s the libusb that crashes. I was focusing to the wrong part of the error message.
Can you please post the output of the commands $ lsusb -d 2b03:?
Can you also please try to open the ZED Sensors Viewer tool and let me know if it starts and provides IMU data?
Hello @Myzhar, thanks for the support, going deeper on this and other problems that i found on my system, i finally found the problem. I had broken packages on my machine that were not updated due to a checkmark in “software and update” settings that prevented the system to upgrade the available packages to newer version. There was a confirmed problem with udev package, that was fixed last year, but my version was blocked before that fix. updating and upgrading after unchecking that option resolved the problem. That was untrackable before trying the ZED and installing ROS2 humble. Finally i can use the ZED camera on my desktop .
Thanks again for your fast answers, help and support!
