dIsplayLinkManager high CPU load

Hello, 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

Hello ! I've the same problem with a Dell Vosto 15 3000 ( And 2 screens) . CPU going at 50-70% when i do something. Thanks for help :)

Hi, 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 dampel

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

I'm now using DisplayLink driver 5.4 under Kubuntu 20.04 and ensured to use a USB 3.0 port of my notebook rather than a 2.0 one (... oh well, I just recently discovered that the ports I was using were not 3.0 ones but rather 2.0...). The DisplayLink now works decently, however the CPU consumption is always relatively high (a constant ~10% at minimum, with peaks at 25% on a 4-core CPU, that means a whole core). However it rarely happens that an application starts to make the DisplayLinkManager process crazy, so that it starts to eat a whole CPU core constantly... In these cases, it's usually enough to minimize that application window or restart it. The problem is that it may be hard to identify which is the actually affected application... I don't know whether the high CPU usage of DisplayLinkManager is a technical limit of how the video over USB passthrough is implemented, however I read a lot of posts on the Internet which say that under Windows there's no such CPU usage problem, so perhaps we can still hope for improvements under Linux as well?

Overall bad display link driver design 

Just registered to confirm that the DisplayLink linux driver is a hot mess that is close to unusable. CPU load exceeds 100% whenever anything happens on a display. There seems to be no solution available. The issue has been around for years, with no fix, reaction or comment from Displaylink. So much for Linux support.
