No associated provider: collides with Nvidia driver?

Hi all!

I've finally managed to install the software on my Debian Bookworm machine? However, now I've entered the configuration phase, I've stumbled upon a new issue: the DisplayLink driver finds 2 graphic cards on my laptop (Intel + Nvidia) but seems to use none of them as providers. The laptop is connected to an i-tec docking station, with 2 x iiyama Prolite screens. The setup works perfectly well with my Win 11 machine...

Here's the debug output:
```

Therefore the only display is obviously the embedded screen. I suspect there's some kind of conflicts with the Nvidia graphic card: how can I confirm this and eventually deactivate the Nvidia card? I must add that the card is (normally) deactivated at boot time through the grub config file.

Thanks in advance for any help!

Start by reviewing /etc/X11/xorg.conf.d/20-displaylink.conf alongside the supplied provider output, then compare how the Intel, Nvidia, and DisplayLink devices are detected on Debian Bookworm. Done would mean a confirmed cause for the missing provider association and documented, reproducible configuration guidance.
