Help with Optimus and external monitor use

[Bob McGowan]

Hi,

I have an Asus Tuf Gaming laptop which has an Optimus configuration, 
with an AMD GPU rather than Intel.


I'm running Debian 11.7

I do not have any of the "other" auxiliary software tools installed, 
such as Primus (primusrun...).


When I run glxgears -info, I see it using the AMD GPU as expected.

Setting __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 
__GLX_VENDOR_LIBRARY_NAME=nvidiaas described in the Debian Wiki 
 
and then running glxgears -info shows it is using the Nvidia GPU, as 
expected.


My problem is that what I want is to use the external HDMI with an 
external monitor.


So in the section of the Wiki page titled "PRIME Render Offload with an 
External Display", I followed the instructions to run nvidia-xconfig 
(had to install it first).


That failed. :(

I finally took a look at Xorg.0.logand discovered the following error:

   [  5116.917] (II) LoadModule: "nvidia"
   [  5116.917] (WW) Warning, couldn't open module nvidia
   [  5116.917] (EE) Failed to load module "nvidia" (module does not
   exist, 0)

What "module" is this referring to?

The kernal module is loaded:

   $ lsmod | grep nvidia
   nvidia_modeset   1204224  1
   nvidia  35528704  19 nvidia_modeset
   drm   630784  19
   gpu_sched,drm_kms_helper,nvidia,amdgpu,ttm

Do I have an incorrect X "driver" and if so, what do I need to 
remove/install?


Thanks for your help.

Bob
