Title:
Ubuntu desktop does not appear on DGX Station A100 discrete GPU by
default

Bug description:
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.
