Hello,
since this is the same problem I’m facing, and I haven’t seen a solution to this on the forum, I’m replying to this thread. Problem:
deviceQuery and nvidia-smi only recognize 1 GPU (of 2 RTX 2080ti), and lspci recognizes both. Perhaps you found a solution? If not, it would be great, if anyone else could help me. Thank you in advance!
Here are the relevant diagnostic outputs:
$ lspci -vvv
