Well, at least from my lspci point of view (before/after disconnect same
output), this seems to be wrong (no dmesg output as well).

Additionally as far as I understand
thunderbolt, it's bundling display port and pci-e into a single channel,
so I'm not sure if this is 100% transparent pci-e + displayport from our
side.

Or, the better question is probably: How should Linux realise that there
is a change (apple monitor with ethernet, usb, co. plugged in) going on?

I can test stuff here, but would be thankful for a round of pointers on
how to debug / approach this.

Cheers,

Nico
