Xorg.0.log

I just upgraded to Ubuntu 18.04.1. Logging in causes a segmentation fault that eventually logs me back out. This only seems to happen when I connect to my laptop dock that has 2 monitors connected to it. This same exact hardware previously worked on Ubuntu 16.04.

Relevant section from /var/log/syslog is below. I've also attached the Xorg.0.log file referenced
