Screens reorganise, failed to enable link training errors in dmesg about 60s after plugging in dock
Could you provide some kernel logs when you are trying to plug the monitor? Right now, I don't even know what driver you are using...
In the mean time, I'm moving this bug to DRM/other, and closing as INVALID. Feel free to re-open once you have added the logs I asked for :)
