dIsplayLinkManager high CPU load
1 Attachment(s)

I have fresh installation of Ubuntu 20.04 LTS oin Dell Vostro 5590 with integrated Intel UHD graphics and dedicated Nvidia GP108M [GeForce MX250]. I use the Dell D6000 universal docking station.

In order to have the display link working correctly with integrated graphic card I follow the post


The display link is now working, however the displayLinkManager process generates huge CPU load after each event (mouse move, change of the displayed content after key press, change of the displayed content by program - htop, video player, etc). The high CPU load is noticeable on all 8 threads.

I suppose, that this is not normal. Exists there some workaround?

Thank you,

Jan Hubeny

You can try steps from this post:
But if you have possibility change you docking station to that witch not require DisplayLink.

I'm looking for such docking station.

Best Regards

Same problem here with Kubuntu 20.04. Monitoring this thread in case anyone from DisplayLink posts something.

Also have this problem, Ubuntu 20.04 on a Lenovo laptop, AMD Raedon Graphics card. Installed the latest version of the driver, however when I plug in the displaylink the DisplayLinkManager process immediately starts eating up CPU. If I drag anything onto the other screen it jumps to well over 100% and starts really stuttering. Seems like a very common issue based on the number of posts I've seen, but unfortunately no resolution!

Actually I do not remember if I checked the CPU usage, but that might be the source why the screen was very laggy and audio choppy. I have system with AMD CPU+GPU and Ubuntu 20.04

Idk whats the status of this project, but I need to admit that since the release of 20.04 the DisplayLink team is not very audible on this forum. Recently there were no replies from them at all.
So well, lets hope a new kernel 5.8 will bring the fix for our issues and this project will not become an abandonware
