Ubuntu drivers eating a lot of CPU. Not always but at least 50% of the times
I have actually a very slow PC because of this:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1541 root 20 0 2343424 51804 2624 S 111.9 1.4 198:49.14 DisplayLinkMana
in other words, DisplayLinkMana(ger) eats a lot of CPU. from 50 to more than 100%
sometimes not.
I think this is an issue, that should be fixed.
Thank you.

Same issue here. newest Linux mint, asus S510UA. DisplayLink constantly uses more cpu than any other program, even when not docked. Program is in /opt/displaylink/DisplayLinkManager

Same issue here. Just moving the mouse CPU usage jumps to 50%.
I frequently have to wait several seconds for the keyboard input to be recognized. -

This is also happening on my Thinkpad T440 running Elementary OS (derived from Ubuntu 18.04).
CPU usage is very high. I have already disabled vsync and disabled animations on the OS level, but to no avail. CPU usage still hovers around 50-70%.

I see this on a Dell Inspiron 2-in-1 quad-core laptop. Just siting there it bounces around between 25% and 45% CPU usage. Simply moving the mouse has it jumping from 80% to 140%. Switching tabs in Chrome. Ubuntu 18.10.

Same here, after watching a video or having a video conference (in Chrome) on a display connected to my D3100 (Dell DisplayLink connector) which is connected to my XPS 15.
The CPU used doesn't stop after I stop watching the video. -

The same here... On a Lenovo T440s. When using a docking station with Display Link and watching youtube or something like this CPU usage of display link process is about 60 %
When conecting via the ThinkPad Pro Dock 04W3948 no issues of any kind. Very sad as this kind of connectors are not common any more on newer devices. -

This is really bad. I'm getting overheating on Dell XPS 15 i9 32GB RAM when using displaylink on Ubuntu 18. I even did some undervolting to workaround a bit of the problem. Solved it a bit, but still get a lot of heating here.

This is happening on a Gen 6 Thinkpad X1 on 18.04 with kernel 4.19.
Up to 20% on DisplayLink CPU use. Makes it the highest CPU user in the system.. -

Same on Ubuntu 18.04 with Mate + marco, although changing to Gnome 3 consumes "only" 10 to 30%. Pls fix.

Is there a fix available for this yet? This has made the product completely unusable with my linux machine?

Travis commented
Is displaylink looking into this?

Same issue on Clevo PH50HP6 Core-i7 HQ 16GB RAM. I see many instances of /opt/displayLink/DisplayLinkManager running and eating more than 20% of the CPU.

I've been using this dock for a few weeks now, and I hadn't noticed this before, because my beast XPS13 can easily handle it. Though I'm having the same problems as before mentioned, I haven't experienced any video issues (only use a single 1080p 75HZ monitor), but even with the DisplayLink disconnected the DisplayLinkManager CPU usage varies between 15-20%. When the DisplayLink is connected it varies between 15-150%.
