[Solved] New MacOS Catalina breaks DisplayLink

[darthjr]

After I updated to 10.15.1 on my MBPr 15 2018 - the display just blinks after plugging in the Dell 6000.

I am running the 5.2.1 Beta 3 drivers now. I tried to rollback to the 5.1.1 but the duel and single display (HTML) were blank.

Help!

Hi, I have the same issue as rarutu.
Right after apple Catalina Update (10.15.1) Display link stop working.
After Installing Catalina and before the last update the dual monitor and everything were working.
Beside the fact that i couldn't charge my MAC from DisplayLink anymore.
However after the 15.1 update nothing works anymore. Only mouse and Keyboard.
If i connect and disconnect the DisplayLink USB type C cable from my laptop and reconnect it My laptop monitor start to flicker like trying to connect to the external monitors. But the external monitors does not turn on.
In attachment there is my log.
It would be great if you could help pr release an update as i can use only the laptop monitor now which is very counter-productive.

Thank you!

So I am not Cyfer, but I was struggling this morning to get it working with the same issue they had. Then I tested plugging in the dock, and then plugging in a separate power cord and poof my displays started working again. I have gone through so many different versions of the driver and am currently on 5.1.1 though not sure it matters which one as 5.2 worked yesterday right after the update to Catalina then stopped working today. Not sure what is going on.

The Charging is not an issue, even before 15.1 i was using an external charger for that. But at least i was able to use the monitors, keyboard and mouse with displaylink.
But now after 15.1 nothing works even if i have the charger connected and connect the Displaylink.
It is clearly a software issue since a Catalina Update broke it.
