Dear users!

Thank you for your constant communication here on the forum and your patience.

We would like to apologize for the inconveniences that you have faced while trying to use our new driver.
We are aware of libdrm issue on our new driver for Ubuntu 20.04

Right now our Engineering Team is working on the resolution of the problem. We should be able to release a fix very shortly as our engineers are already testing the possible solution for this case.

As a possible temporary workaround you may start our installer in this manner:

From console:

Installing Workaround:

LC_ALL=C sudo ./displaylink-driver-5.3.0.28.run

Uninstalling Workaround:

LC_ALL=C sudo displaylink-installer uninstall

This should help you for now before we have a permanent fix done.

Thank you very much for help in developing our drivers and I will be posting here any new information we would be able to share with you!

Kind regards,
Jakub

Many people are having performance issues with the new driver and can't use their display link devices. Are you planning to fix this issues or maybe you already have any solution?

Default ubuntu 20.04 + thinkpad t420 intel

I recently installed ubuntu 20.04. (fresh install)

I use displaylink D3100 to connect thinkpad t420 with intel graphics to view on external FHD monitor. I use X11

When used only on external monitor it lags a lot it's not usable at all. When i use inbuilt display , mirror, extend works ok



Same configuration worked flawless on ubuntu 18.04


PS : tried but same result
make /usr/share/X11/xorg.conf.d/20-displaylink.conf

Section "Device"
Identifier "DisplayLink"
Driver "modesetting"
Option "PageFlip" "false"
EndSection

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

Default Amd Ryzen 5 3500 U vega radeon 8

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
