Black screen on RTX4090 with aurora-dx-nvidia-open #2653

Description

Describe the bug

A long time ago, between update 43.20260217 and 43.20260303 I was no longer able to get to the log-in screen after entering my password at boot. I could use the computer with aurora-dx, so have been using that. I finally gave aurora-dx-nvidia-open another try yesterday and had the same problem.

I finally asked on Discord, and Renner suggested I pull the logs after rebooting back into aurora-dx:

log.txt

AI was able to suggest a solution based on the logs, which I quote below:

The issue isn't with the nvidia-open drivers themselves, but rather with a laptop-specific graphics switching daemon that is inadvertently running on your desktop hardware.

It had me run systemctl mask --now supergfxd.service and I was finally able to successfully boot into aurora-dx-nvidia-open.

What did you expect to happen?

To boot normally instead of into a black screen.
