Hi all,
I’m using with satisfaction CUDA to transcoding tv registrations. I’m trying to configure my system with a 2nd Gpu to increase the performance, but I have a big problem. The system don’t recognize the 2nd Gpu. The Gpu are two GTX1050Ti 4GB
this is the output of nvidia-smi command:
I’m using Ubuntu 20.04.02 LTS with kernel 5.8.0-43-generic and as you can see driver version is 460.27.04 and CUDA Version: 11.2
Following the solutions proposed in others topics, I had launched the following commands and I post the results
lspci |grep -i nv

The problem is securely into the NVRM message, but I’m not able to find a solutions. The nouveau driver are blacklisted with file /etc/modprobe.d/blacklist-nvidia-nouveau.conf other driver also blacklisted (but editing the /etc/modprobe.d/blacklist.conf ) are vga16fb rivafb nvidiafb rivatv
Any help will be many appreaced.
Thank you
