Random display failures

[dan_linder]

I have a Dell Universal Dock D6000 that I am using with my HP Spectre x360 Convertible 15-ch0xx that has an annoying issue. Under Windows 10, it works fine, but if I dual-boot into Linux, everything works for a while, but randomly the displays quit and un-plugging and re--plugging the USB adapter fixes it (or power-cycling the D6000, or rebooting the system).

The USB keyboard and mouse continues to work, as does the audio through the D6000 3.5" headphone jack and the network connectivity.

I have downloaded the DisplayLink log collection tool and ran it on this system. The first one (timestamp 16:30) is right after the displays died, and the second one (timestamp 18:08) was taken right after I un-plugged/re-plugged the USB cable into the port.

This has been a problem even in Ubuntu 19.04 and 18.04 versions - I have now upgraded to 19.10 hoping that it was resolved in later drivers.

Any thoughts on how to help diagnose this annoying problem?
