Completely unusable in Ubuntu 20.04

sproell · 08-17-2020, 06:34 AM

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
