Hi Daniel, I tried removing Removing xorg-nvidia.conf and the following setups:
- nomodeset: hdmi: no display bmc: just a fsck message (blinked sometimes) - no splash / no X sosreport: sosreport-u-DGX-Station-A100-920-23487-2531-000-nomodeset-2023-09-04-fvncavf.tar.xz - nomodeset + blacklist ast hdmi: no display bmc: just a fsck message (blinked sometimes) - no splash / no X sosreport: sosreport-u-DGX-Station-A100-920-23487-2531-000-nomodeset-blacklist-ast-2023-09-04-sasnfpi.tar.xz - blacklist ast hdmi: no display bmc: just a fsck message (blinked sometimes) - no splash / no X sosreport: sosreport-u-DGX-Station-A100-920-23487-2531-000-blacklist-ast-2023-09-04-hcfupsp.tar.xz The sos reports are in a shared Google Drive: https://drive.google.com/drive/folders/1FVHt2IMGsOyAsQ5U-z0kiqEFMD8NaWzh Without the ast blacklist or the nomodeset, the behavior goes back to: - no /etc/X11/xorg.conf.d/ file: Splash and X on BMC Display - /etc/X11/xorg.conf.d/xorg-nvidia.conf: no splash, X on HDMI -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/2033418 Title: Ubuntu desktop does not appear on DGX Station A100 discrete GPU by default Status in xorg-server package in Ubuntu: New 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.
