Displaylink CPU Usage high in Ubuntu 18.04

brice · 11-05-2018, 10:18 AM

I'm having exactly the same Problem and created an account just to put my voice behind the cause.
So i'm using a lenovo miix-520 with an ubuntu 18.04 and displaylink is routinely using 100-200% CPU load on multple processes. This is way overboard. I'm not even doing anything remotely graphically heavy. As soon as the load increases the performance goes into the cellar...
A quick google search tells me that this problem seems to be around for over a year now. Will this problem ever be addressed or should linux users just ditch DisplayLink?

Looking at how many threads are here with a high CPU load on Ubuntu and how little anyone from DisplayLink cares about it, it looks like they are giving a **** about Linux support. It's a real pity ... DisplayLink could be such a great solution, but ...

Unfortunately I didn't look in this forum before I bought this stuff ... I do really regret having bought a dock which is using DisplayLink ...

I have the same problem but using Antergos (Arch Linux). CPU usage is continually high, even when I'm doing basically nothing on the computer.

Yup, basically if you're a professional who uses linux in your day to day work, you are way better off just getting a pure thunderbolt 3 dock. It's sad how bad linux support is for displaylink. They don't want to provide any regular updates/improvements to the linux driver yet won't open-source it either. The ridiculous thing is that people who use linux are usually power users and more likely to use multiple monitors...

I will never ever buy a display link dock again...

same here, running mint 19.1 with latest 4.4 of the driver and cpu rockets to over 150% on my fujitsu e754 lifebook with the displaylink process the cause.

I've since ditched the driver and looking at alternatives and wil simply opex it.
