Displylink Bpfilter issue
 

On Ubuntu MATE 19.04 using a Dell D3100, plugging it in or logging in with it plugged in causes the screen to come up with 'starting bpfilter' and the forcing the user to log in again. Seems bpfilter has some sort of issue with displaylink which is causing Xorg to crash completely forcing the user to start a new session. However once the user logs in again it works fine until the computer is shutdown.
I have attached the debug zip after being unable to find any hints in the logs.
