Hi, so I bought a Satechi Thunderbolt 4 Dock. The device is recognized by NixOS and a Fedora LiveCD image. An external monitor connected to it is detected, configured and active, but the monitor never detects the signal, just stays there in standby mode.
Curiously, the same dock, with a Lenovo P14s with AMD processor and just USB3 (no Thunderbolt), detects the monitor and is able to show an image.
Well, I’m still in time to return this Dock to Amazon for free, probably I will give it a try to one of the mentioned in this thread that works out of the box.
