Bug#969709: nvidia-modprobe: Notebook screen does not come up as nvidia-drm is removed

[ganomi]

Package: nvidia-modprobe
Version: 450.66-1
Severity: normal

Dear Maintainer,

Environment:
Thinkpad X1 Extreme Gen
GeForce GTX 1650 Mobile / Max-Q
4K OLED
Debian Sid

Issue:
My screen does not light up while sddm is loaded and running. This was always
working fine before. The issue was introduced with recent upgrade.
It seems that nvidia-drm is no longer loaded. Unfortunately X does not come up
on my notebook screen without having the nvidia-drm loaded.

X works on external monitor without nvidia-drm.

Workaround:
switch to console
modprobe nvdia-drm modeset=Y
systemctl restart sddm

sddm setting:
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
xrandr --dpi 144

Observation:
/etc/nvidia-modprobe.conf unloads the nvidia-drm

Thanks,
Jiri
