Fix the problem where DisplayLinkUserAgent eats 38% of my CPU
OS is windows 10, DLUA is 184.108.40.206.0. This often gets in a state where the user agent sets there using between 35 and 38% of CPU.
7.9 M5 release for Windows is now available from our download area. Please create a support ticket for individual investigation if you meet any issue.
I have an HP comaq (not sure what exact model) with an ASUS Nividia GeForce 210 silent video card and two monitors hooked up to the VGA and the DVI inputs on the card. do i need DisplayLink if i'm not using a USB cable to connect my monitors?
same issue here...Systems run on Win 10 professional with DisplayLink 8.1.843.0. As soon as you move your mouse from the internal display to the external display/s that are connected to the usb3 dockingstation the CPU usage on process "WUDFHost process (Windows Driver Foundation -User-mode Driver Framework Host Process)" gets to 20%-80% and the mouse movement is "lagging" hard -> working is not possible (even the i7-6700HQ cant handle the CPU usage of the above mentioned process).
I´ve tried to install 8.2 Beta 2 08 Mar 2017 to resolve the issue but the problems still exists.
The newest graphics card driver from Nvidia (from 09.03.17) and chipset drivers are up to date.
Problem occures on every type of notebook (Dell XPS, Schenker XMG and Lenovo Thinkpad).
Hopefully this issue gets resolves soon or maybe someone finds the cause and a possible workaround for this issue...
DisplayLinkUserAgent does not exist on Windows 10 Anniversary Update onwards (v1607).
Same issue here. Windows 10 and DisplayLink 8.1.843.0 (dlidusb.dll). Just moving the mouse generates load on WUDFHost process (Windows Driver Foundation -User-mode Driver Framework Host Process. Are you working on a solution?
Also seeing this issue with my Surface Book together with a Toshiba dynaDock U3. The surface is on latest Win10 1607 and the driver I currently have installed is 8.1 M0 as of Dec 18th (8.1.843.0)

I am having an issue with HPElitebook 820G3 model and I am using Targus ACP71EU
Would it be possible to get a patch so that the CPU does not go high and in my case it jumps to 80% constant UP and down, which is a nightmare for any developer machine.
Thanks in anticipation
Experiencing similarissue with Dell Latitude E6440, Win7, while connected to Dell 3100 USB dock. DisplayLink User Agent is using between 30 and 40% CPU. I installed 8.1MO and the issue persists. Thank you.
DisplayLink STILL haven't fixed this? It's been years
What is the latest recommendation? Other than buy different hardware
Why is the agent jumping from 2-3% CPU to 25% CPU or higher and not releasing. I am forced to stop the service and restart and that usually fixes it until the next time it jumps to 25% or higher. I have Windows 7 Dell 7450 i7. I have replaced by machine twice. My dual monitors and my Dell D3100 dockingstation twice. Not sure why me or what is happening specifically. I am using version 8.1.848.0.
Help me please!
I have S.O. Win7 and displaylink M8 v.8.0.923.0
Displaylink working whit 25% CPU. Constant!!!
Help me please!
I have same problem. My system is W7 and displaylink is last version M8 v. 8.0.923.0.
Help me please!
Same problem here using Ubuntu 16.04. The displaylink process works always as if everything were being drawn to the monitor connected with the displayport adapter.
Using a different window manager than Compiz solves the problem. Also disabling OpenGl in the compiz settings does it, but that leaves you with an unusable desktop where you can't move any windows.
At the moment, when using Linux with a displaylink adapter, the possibilities are these:
a) high CPU load with compiz
b) low CPU load without compiz
Unity needs compiz, so Ubuntu/Unity is going to have a high CPU load when watching videos or moving windows, or playing.
Also seeing 20-80% CPU usgae on Ubuntu 16.04, with latest driver (May release).

Hi guys, same problem here, ubuntu 16 up to date, last version of driver DisplayLink for ubuntu, the process DisplayLinkManager hit 15-20% CPU all times, any idea for stop this process when i don't use the displaylink dock ?
Dell XPS 13 9333 running Ubuntu 16.04
DispalyLinkMana consumes 75% of cpu
Hi, for me the solution was to exclude the files described in the link below to be scanned for malware.
Hello Tom, why don't you also reply to your tech support ticket with a new set of logs so we can actually look at it? I'm afraid you're an isolated case but we can look into it if we get some information to do so.

This did not resolve the issue for me, in fact it made it worse. Now this causes my Intel Display Driver to crash, after which one of my monitors flickers and is unusable until a reboot. The driver used to crash occasionally before the patch, but it would just crash and I could then kill the DisplayLinkUserAgent process to restore functionality.

Yes yes yes me too with an XPS 13. Just had something like 38% and everything moved like it was in molasses.
