Status update from me.

The hang with nvidia-drm.fbdev=1 is caused by gpu-manager.service which is:
WantedBy=display-manager.service
Before=display-manager.service

In my previous testing delaying gdm.service with udev-settle really just caused to delay gpu-manager.service which fixes this issue.

I'm now thinking that gpu-manager.service is also the cause of bug 2063143.

It also explains why I don't hit any of these bugs in Fedora, as gpu-manager.service is only shipped in ubuntu: https://github.com/canonical/ubuntu-drivers-common/blob/master/share/hybrid/gpu-manager.c
