It sounds like the main problem therefore is the Nvidia X driver. It's refusing to light up HDMI without a custom config explicitly telling it to use "PCI:193:0:0". But this might be Nvidia's intended behaviour so I recommend checking the docs for solutions first:
https://us.download.nvidia.com/XFree86/Linux-x86_64/535.86.05/README/index.html And contacting Nvidia for help second. P.S. The Nvidia website recommends driver 460 for the A100. Also the installed driver version sounds like it's from nvidia-graphics- drivers-535 (desktop), but also there are some nvidia-graphics- drivers-535-server packages installed? So I wonder if this is just a bad choice of drivers for the hardware. ** Package changed: xorg-server (Ubuntu) => nvidia-graphics-drivers-535 (Ubuntu) ** Also affects: nvidia-graphics-drivers-535-server (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-535/+bug/2033418/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
