Here it is: https://www.displaylink.com/downloads/file?id=1576

Please verify that version and if you would face any issues inform us.

Thank you very much for your cooperation!

Best regards,
Jakub

thank you for the fast fixing. The installation of the new driver with

Code:

$ sudo LANG=C ./displaylink-driver-5.3.1.34.run

and

Code:

$ sudo ./displaylink-driver-5.3.1.34.run

is working fine.

Unfortunately the perfomance issue maintains. Do i miss something?

I am using a Lenovo Dock 2 USB-C with USB-A

I can confirm Tiberius's issue.

Good evening, the lag are very evident and even if imposed the effects of plasma with xrender are still visible. If I remove the dock everything goes back to normal. I am attaching the debug file.

In fact, on ubuntu 18.04 I had no problem with any lag.

It doesn't allow me to attach the file. I enclose it with connection via gdrive

Same here. Big lag's when using external screen only.

Confirming there is still an issue with the latest package for Ubuntu 20.04. I recently upgraded 20.04 and installed the latest DL package, displaylink-driver-5.3.1.34. Now if I close the lid, the UI lags 3-5 seconds on input (e.g. button click does nothing for 5 seconds). Opening the lid and the issue immediately goes away. Nothing from htop seems to indicate this is in anyway tied to CPU/memory load.
