Any advice to get unofficial docks working with Pinephone?

Hi,

I’m wondering if there is anything one can do to make other docks that are not bundled with the Pinephone package work? I’m trying to connect my Pinephone (original) to a Dell dock and keyboard and mouse work but no screen output. The dock that came with the Pinephone works, even screen output. Are there any packages one can install or other tricks one can do to make third party docks work?

This is on latest Manjaro-Phosh.

Any tips would be greatly appreciated!

Sorry not an answer. I have the same problem with a cheap generic USBC dock ie the mouse and keyboard work but there is no video output. If there is an answer, I’d love to hear it.
