460.73.01 works fine when I disable the integrated graphics on my laptop (a Thinkpad P52). But when I reenable integrated graphics, and attempt to use render offload (as per [https://wiki.debian.org/NVIDIA%20Optimus](https://wiki.debian.org/NVIDIA%20Optimus) and [Chapter&nbsp;34.&nbsp;PRIME Render Offload](https://us.download.nvidia.com/XFree86/Linux-x86_64/450.57/README/primerenderoffload.html)), Xorg seems unable to find the nvidia driver. Forcing it to load the driver results in this error.

```auto
(EE) Failed to load module "nvidia" (module does not exist, 0)

```

The kernel modules appear to exist fine (lsmod reports they’re loaded; nvidia-smi provides useful results).

Thank you.

The driver should be in the package  
[xserver-xorg-video-nvidia](https://packages.debian.org/de/sid/xserver-xorg-video-nvidia)  
But since it’s installed in a debian-specific directory /usr/lib/nvidia/current the xserver has to be pointed to it, e.g.  
/etc/X11/xorg.conf.d/11-nvidia-driver.conf

```auto
Section "OutputClass"
    Identifier "nvidia-driver"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    ModulePath "/usr/lib/nvidia/current"
EndSection

```

Thank you. That does work. I have reported this issue to Debian here [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988200](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988200).
