I have two GPUs installed in my computer. 1 - Nvidia GT 710. 2 - Nvidia GTX 1650.
Per lspci | egrep -i “vga|display|3d”, the system sees my two graphic cards.
01:00.0 VGA compatible controller: NVIDIA Corporation GK208B [GeForce GT 710] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation TU106 [GeForce GTX 1650] (rev a1)
However, nray-desktop:~$ nvidia-smi -L finds only 1 GPU
GPU 0: NVIDIA GeForce GT 710 (UUID: GPU-f256899a-8d0b-2405-0a4d-d5f147d78092)
Furthermore, ray@ray-desktop:~$ sudo dmesg |grep NVRM
[sudo] password for ray:
[ 2.596632] NVRM: request_mem_region failed for 0M @ 0x0. This can
NVRM: occur when a driver such as rivatv is loaded and claims

Hence, I have a problem of not being able to use the second GPU.
