I had this same issue - if it's the same thing, it turned out that there are firmware issues and that the up-to-date firmware was only available for Windows (this may have changed, it was ~3-4 months ago). Lenovo's officially putting their updates on LVFS, but in practice it seems neglected. I spent a day or two stubbornly trying to extract the updates from the Windows binaries, eventually resorted to booting into Windows and updating firwmares on both laptop and dock that way. No issues since.
If it still doesn't work you can fall back on displaylink drivers in a pinch.
- exceptione 6y agoUpdating the firmware changed nothing. On the product page I don't see linux compatibility even mentioned.
- Legogris 6y agoThat's unfortunate. FWIW I'm using both an old-style dock (ye olde bottom connector) and the Thunderbolt 3 Dock with a T470s and a T480s with Arch and NixOS. Displayport and HDMI both working fine after first doing the latest updates using fwupd and then running additional updates for laptop/controller/dock from Windows (first step probably redundant). If it's the Thunderbolt 3 Dock, it can be worth checking that you're using the right ports/cables (not all USB-C ports are Thunderbolt ports) and that there's sufficient power (there are different power adapter alternatives and the 135W brick that shipped with my dock wasn't enough by itself so still need a separate charging cable for the laptop).
