Window Manager: niri 25.11
Use niri debug options to ignore nvidia driver:

debug {
    render-drm-device "/dev/dri/renderD129"
    ignore-drm-device "/dev/dri/renderD128"
}

To Reproduce

Use same parameters

After unload 'nvidia_drm' module, gpu entered d3cold.
This is probably the issue, So is it expected that gpu won't go to d3cold when nvidia drm module is loaded,even if no external monitor is plugged in?

[Binary-Eater]

I believe this issue is likely a dup of #759. Would you mind testing if loading nvidia_drm with fbdev=0 resolves the issue with entering D3cold?

yes, loading nvidia_drm with fbdev=0 did resolve the problem, tested in KDE(KWIN_DRM_DEVICE set to amd gpu), tty.
but still no on niri, i guess niri somehow wake nvidia like nvidia-smi and nvtop did, it`s not your issue.
thanks a lot.
