Hello,
What's the status of the LED on the dock when you reboot and it's not working?
Does the dock stay asleep, or does it wake up?
When the boot with the screen not working and login. If you open the DisplayLink Manager app, do you see any device/monitor recognised?
Finally, we have a tool to get logs that could be connected whilst in error, as it would capture what is "seen" by the computer and the app, and what's not.
