Subject: please ship NVIDIA's runtime D3 (RTD3) udev rule so the dGPU
can power off when idle

Dear Maintainer,

On a hybrid-graphics laptop (Intel iGPU drives all outputs, NVIDIA GPU has no

 outputs), the NVIDIA GPU never enters runtime D3 with the Debian packages,

 even though the driver reports RTD3 as supported. As a result idle power draw

 stays very high.

System:

HP Victus 16-d1xxx laptop

Intel Alder Lake-P Iris Xe (all display outputs, including HDMI/DP) +

 NVIDIA GeForce GTX 1650 Mobile / Max-Q (TU117M, Turing), no outputs

Debian 13 based (Pardus 25.2), kernel 6.12.113+deb13-amd64

nvidia-driver / nvidia-kernel-dkms / nvidia-suspend-common 550.163.01-2

GNOME 48 on Wayland (gdm3 48.0-2)

What happens:

 After the driver is loaded, /sys/bus/pci/devices/0000:01:00.0/power/control

 is "on", which disables runtime PM for the device. runtime_suspended_time

 stays at 0 and the GPU remains in D0 even when no process uses it
