Hi All,
I'm currently using the DELL D6000 Dock with two 1080p monitors connected. The problem is that the dock randomly disconnects and reconnects a few seconds later. Has anybody had similar issues? I'm also getting a segfault from the DisplayLink Manager (see log below)... PS: This issue does not occur using Win 10 (Dual boot). Below a few details about my setup: Laptop: DELL XPS 13 (9360) - Intel Core i7 7500U, 8GB RAM (Latest BIOS etc) Graphics: Mesa Intel® UHD Graphics 620 (KBL GT2) Dock: DELL D6000 (2 x 1080p monitors via DisplayPort) (Latest firmware provided by DELL) OS: Ubuntu 20.04 LTS on Wayland (Kernel 5.4.0-40 - UEFI) Please let me know in case any other logs are required. Thanks a lot in advance! Viktor Code:

I also noticed that once the machine is shutdown the D6000 dock doesn't go to standby. Even after disconnecting the USB-C cable the device remains active (indicated by the white power led). On Windows this turns orange... Last edited by LnxUsr; 07-06-2020 at 10:32 PM. |

Managed to solve the problem. After a fair of research I stumbled across the following Wiki: https://wiki.archlinux.org/index.php...ocking_station
As it turned out Pulseaudio is sending the audio device to sleep which in turn brings the whole Dock down. In order to avoid this I had to comment the below module out and restart the machine. Code:
### Automatically suspend sinks/sources that become idle for too long # load-module module-suspend-on-idle |

The latest DisplayLink drivers are installed. I will disable the PulseAudio module per your instructions and test. Resolving this issue would be such a relieve. |

This resolved the issue for me as well.
Ubuntu installed on a thinkpad, with a thinkpad dock. |
