[UPDATE] I also tried the Displaylink driver version 5.3.1 from 5th of may 2020. No Monitors externally are detected! So less functionality! I tried this version as well, 'cuz I installed the last working version somewhere in the first half of 2020. Will try now 5.3 and 5.2 (even this is not for UBUNTU 20.04).
[/UPDATE]
[UPDATE2] Drivers 5.2 and 5.3 install/deinstall and reinstall to 5.4 has lead to a system, where external monitors are not detected anyway. So at least the system is now complete broken. I followed that deinstall instructions with
sudo displaylink-installer uninstall
and rebooted afterwards every time. The installation process does not seem to be very stable.
[/UPDATE2]
I am using a HP USB-C Docking Station for my external periphery devices (USB keyboard and mouse, Audio, Ethernet and 2 External monitors via Displaylink driver), so that I can easily switch between my working laptop running windows 10 and my UBUNTU laptop (ASUS ROG G752VS). Till yesterday's update everything worked fine, after the update, Display link drivers did not work. So I downloaded today the latest Display Link drivers from here (I followed all steps). After the rebooting external monitors were detected nearly like before. Now my internal monitor is also detected and I cannot turn it off (either by setting it to "off" on Display settings or by just closing the laptop's lid, the system freezes (You see the monitors with a frozen mouse pointer, and no keyboard). So I cannot even run a terminal hitting "Ctrl-Alt-F[x]".
After system freezes nothing works and you have to turn off the computer by pressing "on" for 4 seconds. I varied switching the main monitor to one of my main (external) displays, which works. But if I turn off any of the monitors (so regardless whether internal or externally attached to the usb-c dock) it freezes. I also tried ARandR to exclude system internal software tooling problems. But the problem seems to lie deep in the system, I assume of the kernel or its display link module.
My HW Configuration:
- Two FULL HD monitors connected via DisplayPort and link to the USB_C dock
- ASUS ROG G752 VS running Ubuntu 20.04 LTS
- USB Mouse and Keyboard
- Logitech Sound connected analogly to the small jack of the USB-C Dock
- USB-C Dock of HP connected to USB-C/Thunderbolt of my ASUS ROG G752 VS
My SW config:
- Ubuntu 20.04 LTS with last update of Aug 15th
- Display Link driver v.5.4 from synaptics from Apr 6th 2021

Can anybody give me a hint, what else to try to fix/workaround this issue?
By the way, Does anybody knows, when Display link drivers are flawlessly intergrated into the kernel anyway?
Thanks a lot in advance! Please help!
