I have a Lenovo ThinkPad E460 and a Lenovo ThinkPad OneLink Pro Dock.
Everything works fine, except for the external screen ports on the dock.
When I plug in an external screen to the DVI or DisplayPort, the system
freezes. I've attached a screenshot of the errors I get.
The setup was working fine in Windows 10. The HDMI port on the laptop
works fine.
Some information on the system:
