Shutdown Required for Monitors to Work

[mat21]

I have a Macbook Pro 15-inch, 2019, Mojave version 10.14.6 with a Dell D6000 Dock and 2 Dell monitors. No matter which version of the displaylink software I have installed, the external monitors won't work unless I shut down my laptop, plug the dock in, then power it back up. If I then unplug the monitors, I have to shut down and power on with the dock connected in order to get them to work.

This used to work, but I had to factory reset the laptop for an unrelated issue, and now I can't get it working again. This is a huge pain since I usually take my laptop to several meetings throughout the day and have to shutdown and start back up every time I leave my desk.

Hi,
1. Can you test yours setup with new 5.2.1 drivers?
You can download it from here:
https://www.displaylink.com/downloads/file?id=1478


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

3. If hub firmware update does not help then please submit your logs using that tool:

I tested with the 5.2.1 drivers, same results. It works if I start up the laptop from shut down with the dock connected, but as soon as I unplug and try to plug back in, I have to shutdown and start up again with the dock connected.

The link to the firmware update utility you posted is broken. I did some searching and couldn't find a firmware update utility that runs on OS X, so that won't work for me.

Also, I should point out that this did work at one point with a certain version of the displaylink software. I updated to Catalina and at the time the displaylink software didn't fully support Catalina, so I did a factory reset to go back to Mojave, and now can't figure out which version of DisplayLink was working.

I ran the diagnostic tool and it produced a zip file, do I just attach it to this thread?

Having exactly the same issue as this. The 5.2.1 driver release notes say the "replug" issue is fixed in this version - it is clearly not.

As above this means every time I unplug and go to a meeting and then come back I have to reboot my MBP to get my screens working again. Super irritating!

Can this please be looked into.

OSX: 10.15.2
DisplayLink: 5.2.1
Dock: Targus DOCK190

I've tried at least 13 different versions of the display link software, and all do exactly the same thing which normally makes me think its an issue with OS X and not the software, but this is a fresh install of Mojave which definitely works for some people.

I submitted the logs with the tool, so hopefully they can recommend a workaround. Shame the log files are encrypted or I'd probably have been able to figure this out for myself months ago.

Updating the firmware on my D6000 dock finally fixed this issue.
