Hello everyone,
I have a Lenovo ThinkPad T480s laptop running Fedora 39 Kinoite. I would like to use it in a multi-display setup, so I am looking for a docking station. The laptop has a Thunderbolt 3 port. I have attached the details of my device at the end of the post.
People on Reddit are writing that "all Thunderbolt docking stations should work fine" and that's obviously not the case... I have this Dell Thunderbolt Dock (WD19TB) at home from work and the displays work when I plug it into the laptop but, for example, my mouse (connected via USB-A) doesn't work. When I connect it to the DELL laptop provided by the company, there are no problems at all.

Docking station requirements: Ethernet, 3x USB-A, 1x DisplayPort, 1x HDMI.
I have two 1080p displays: 75Hz and 165Hz. Obviously I'm not going to be playing any high-frame-rate games on this laptop, but even on a desktop it's sometimes nice to see a slightly higher refresh rate. So if it's possible, I'd like it to be able to display things above 60Hz...
I also have a Steam Deck OLED and would like to be able to use this dock with it.

I don't want to spend too much money on it. Do you have any experience in this area and can you help me choose?

I am from Poland if it helps in any way (maybe some brands are not available here).

    Thanks for the link! I hadn't come across this site before and it explains a lot.
    For the Thunderbolt 3, I had the security level set to "User Authorization". I remember KDE Plasma showing me a popup asking for authorization for the Thunderbolt 3 port. I think I will just turn it off to make sure the docking station has the correct permissions. *removed externally hosted image*

    Secure boot has already been disabled.

    When I get home, I'll write about what I've achieved with this DELL docking station when I've finished checking it all out. But it looks like that these problems may be caused by the Thunderbolt implementation used in the laptop, as you wrote...
