Can't enable modeset on boot for wayland

I am using JP 6.0.
When I’m following Weston (Wayland) — NVIDIA Jetson Linux Developer Guide 1 documentation everything works.

But when I do the following:

  1. Disable GDM
    systemctl disable gdm
  2. Add nvidia-drm autoload by adding a line “nvidia-drm” to file /etc/modules-load.d/nvidia.conf
  3. Add nvidia-drm param by adding a line “options nvidia-drm modeset=1” to file /etc/modprobe.d/nvidia.conf
  4. reboot
    In that case weston won’t start:

If after that, without reboot, I remove nvidia-drm module and load it back, sometimes weston will start, sometimes the system will hang
modprobe -r nvidia-drm
modprobe nvidia-drm modeset=1

If I remove /etc/modules-load.d/nvidia.conf file and manualy modprobe nvidia-drm everything works:

Hi,
If you would like to enable Weston as default GUI, we suggest develop it from minimal or basic rootfs:

Root File System — NVIDIA Jetson Linux Developer Guide 1 documentation

The environment is clean and without X. Please try in the environment and check what commands are required. And then run the commands in startup. There are some examples in

Jetson AGX Orin FAQ
Q: How to autorun an app or commands at startup?

Thanks for your reply!

In the production I am using custom build rootfs.
I just tried to reproduce the issue in the vanilla environment.

Currently I have solved the issue by creating systemd unit that runs modprobe nvidia-drm after reaching multi-user.target, and using /etc/modprobe.d/nvidia.conf to configure modeset=1.

But I assume that loading nvidia-drm module on startup using modules-load.d should work? Or I should use some udev rules?
