You have been subscribed to a public bug: The DGX Station A10 has various display options. The BMC provides an emulated device (Aspeed controller), a physical BMC controller (NVIDIA Quadro T1000 Mobile), and a discrete GPU card with 4 DisplayPort outputs (A100 SXM4 80GB). See the user guide[*] for a diagram.
In a default Ubuntu Desktop 22.04 ('jammy') install, nothing appears on the A100 DisplayPort output. NVIDIA DGX OS - a derivative of Ubuntu - works around this by installing a service that generates an xorg config file dynamically based on the "OnBrd/Ext VGA Select" setting (aka "dmidecode -t 11"). I'll attach samples of those files here. Replacing the default Ubuntu xorg.conf file with the sample xorg-nvidia.conf file on a default Ubuntu Desktop install is confirmed to enable output.
