Hello all

I have an AWS G7e instance with an NVIDIA RTX PRO 6000 Blackwell Server Edition GPU.
The GPU is set to MCCD mode, and I cannot switch it to WDDM mode via command line.

I tried the Display Mode Selector Tools, but with no luck

Do you know how can I switch the mode from MCDM to WDDM?

Thanks

Hello @luca.costantino, welcome to the NVIDIA Developer forums!

First of all, why do you need WDDM mode for an AWS instance? The typical use case for WDDM is if you need a graphical (Windows) output.

You should also check the output of --listgpumodes which should show the possible modes of the GPU assigned to you. It can very well be that the AWS provided GPU does not allow setting that mode.

Hi Markus, thanks for your reply

It seems that the only exposed mode is compute, so I guess there may be some configuration to be done to the AWS instance? Any idea of what that could be?

I need to switch to WDDM because I have a specific simulation software that refuses to launch otherwise…

Sorry, I don’t know how AWS sets up their instances. I would assume there are configuration options before they are provisioned to customers. You can check Amazon Web Services (AWS) - NVIDIA Developer Forums and see if that kind of question came up over there before.

Note to my future self, and to others with the same issue.
Installing the GRID drivers did the trick! :)
