Hello,

I use Azure Cloud to rent a Standard_NV6ads_A10_v5 machine (VM).
It has this GPU A10 Tensor Core GPU | NVIDIA

I installed Ubuntu 22.04, Nvidia drivers and UE5.3.
When i try to launch UE Editor I got immediate exit and in logs can see something about there is no video device…

Any advice appreciated!

Hi there!

Just to confirm that the drivers are installed and detecting properly, what do you get when you enter “nvidia-smi”?

This is a log I got from the Editor app:

Actually the problem has been solved.
I can start now UE without any bugs on Ubuntu 22.04

Hey, I’m tackling a similar issue with UE5 and a 3090. I was wondering what version of UE have you built? Currently trying 5.3.2

Actually we rebuild the whole UE from sources + Pixel plugin also has been built from sources.
