[Solved]Only one of two dedicated GPU's are detected
I have two GPU's in my PC, an AMD Radeon 6700 XT and an NVIDIA RTX 2060. I wanted to use the RTX 2060 in a gaming VM, but the pci would not appear. Here's what I see from lspci | grep VGA:

Re: [Solved]Only one of two dedicated GPU's are detected
There's no trace of the nvidia GPU nor an unidentifieable device.
=> Badly seated or underpowered (6/8-pin connector)?
Also consult the board manual on which slots are available for 75W supply.

Re: [Solved]Only one of two dedicated GPU's are detected
I unplugged and replugged the 8 pin connector, and the gpu now shows up. Thank you.

Great.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
