Default Same here

I am using the new dell xps 9300 connect to the dell d6000 running ubuntu 20.04 and unfortunately this is run extremely slow. On ubuntu 18 it all worked just great and now on the 20.04 its a nightmare . I have to leave my lid open to be able to work using the monitor. Thank you

I have the very same issue on my Dell XPS 13 9380 with a fresh Ubuntu 20.04.1 installation. It works well as long as the laptop display is in use. When I turn off the laptop display and want to use only the two monitors attached to my USB-C dock, the system becomes unusable.

* OpenGL version string: 4.6 (Compatibility Profile) Mesa 20.1.5 - kisak-mesa PPA
* DisplayLink 5.3.1

It worked well on the same machine using Ubuntu 18.04.

*Fix*

Applying the XServer patch seems to solve the problem: https://www.displaylink.org/forum/sh...ad.php?t=67148

The same problem with my Dell.
The patch helped for couple months, but it stopped working recently for some reason. I updated everything in Ubuntu and applied the patch again - external monitors do not turn on at all. DisplayLink device is visible, network is working via it, but not the displays.

I can share specs, versions if that helps, just please tell what you need to know.
But it doesn't look like DisplayLink is keen on solving this problem.

Don't know how it was in Ubuntu 18.XX, but I'm really pleased with the performance on Ubuntu 20.04 now. I'm collecting all my efforts in a Debian package, which allows to install the driver incl evdi and only requires a reboot.
If there is anyone who has a workaround or whatever solution for the throttle after a closed lid, please let me know!
Apart from that all works nicely (including asking for license agreements and a clear note that I'm not owner of the software included in my package).
