reporting an issue in debian based OS

["b.mc6" <b.mc6@protonmail.com>]

I have an issue to report but don't know how to go about it. Here is the issue-

Hello,

There seems to be some issues with the 'ThinkPad USB-C Dock Gen 2' and some operating systems that are based on Debian. I am not sure if this is the correct place to let a developer know but I have tried using the 'ThinkPad USB-C Dock Gen 2' with both Linux Mint and MXLinux and had the same issues with both. As they are both based on Debian I thought the issue should be raised here. Issues are-

1. Ethernet connection through the dock runs slow and then turns on and off.
   
2. Hdmi connection through the dock gives colour issues on screen, everything is darker than normal.

There is more details about the issue on the linux mint forum here-

but there is no real solution.

I believed in time the issue might be solved with kernal updates but the dock remains broken for some Linux users.

Thanks.
