Default [Solved] New MacOS Catalina breaks DisplayLink

I have installed the New Catalina MacOS however it appears to break the current release of DisplayLink

This is more of an FYI for others rather than a cry for help I can live without it until DisplayLink provide an update

Update:
When I say broken I mean I can see the mouse pointer but both external monitors are plank only my laptop screen is visible. Both network and mouse and keyboard all work without issue.

Update2:

I think I have fixed my problem under System Preferences / Security & Privacy / Screen Recording put a tick in the DisplayLinkUserAgent.app

This seem to solve my problem

I don't have the DisplayLinkUserAgent in the ScreenRecording tab.

In terminal :
Code:
cd /Library/PrivilegedHelperTools/DisplayLink/DisplayLinkUserAgent.app/Contents/MacOS
./DisplayLinkUserAgent
This will popup a message that Terminal wants to screenrecord.

Driver tested : 5.1.1

I tried the suggestion, but it didn't work for me. I also onl . installed the display link driver after I upgraded. We moved offices yesterday and we are using display link docks. Anything that might make it work?

Neither do I, and I've re-installed Cataline 2x now, and DisplayLink 5.3 three times, but the DisplayLink UserAgent box never appears in Screen Respond box. I manually put it into Accessibility, but no luck getting my monitors recognized: they don't even appear on the "Display" in System Preferences.

Puzzled.

We have identified that part of Dell D6000 docks produced between mid 2018-mid 2019 contains USB Hub firmware issue that was uncovered by macOS Catalina 10.15.1 release.

There is a for that.

Please update your dock hub using "Dell Firmware Update Utility":

@davidwiens
If hub firmware does not help then please submit your logs using that tool:

Submit the logs to who? email?

I am running the latest 5.2 driver, Catalina 10.15.1 and I get the same as many others. Nothing shows up in my Screen Preferences and my screen is black.

My kext is showing loaded properly and notorized. I disabled SIP and touched /Library/Extensions as well. I don't get any popup about allowing access for Screen Recording and it doesn't show any apps listed for Screen Recording in my System Preferences->Security->Privacy.

I am willing to try anything at this poing.
