I have the same problem!
The problem is really annoying and the system load so high that it is hardly usable, please fix this! - Lenovo ThinkPad T480s - Intel i915 chipset - Ubuntu 18.04.3 LTS - Kernel 5.0.0-31-generic - Displaylink driver 5.2 |

I think that this is causing issues in Gnome under X on Ubuntu 19.10 as I'm getting occasional hangs and am getting kicked out of Gnome, followed by X freezing, an inability to get to the consoles and the only resolution is pressing the power button to start the shutdown process or REISUB.
The CPU usage under X is 200%. Unfortunately I can't use Gnome under Wayland either as it crashes (when trying to edit the screen layout) so that's not a workaround for me. |

I too have this problem with 19.10 and drivers 5.2.
This issue makes docking stations unusable with Ubuntu and my latest XPS 13. I tried different dock models and found myself stuck each time with this high CPU problem, With Wayland I get a crash as soon as I change any display setting, otherwise it works but slowly because of the ridiculous CPU load. |

The issue where changing display settings causes the Wayland session to hang has been seen on Fedora too: https://github.com/displaylink-rpm/d...rpm/issues/112

is there any workaround for this problem?
Im running on Ubuntu 19.04 with the Dell D6000 Docking Station As i use it with a Laptop the high CPU-load makes the laptop unusable because it gets very loud.... please some help... my colleagues in the company running windows 10 have no problems at all with those docks and the same laptops... and now im the stupid linux-guy with the crappy drivers? I think this is such a massive bug, that the linux-drivers are defacto useless... i have - keyboard - mouse - 1 monitor with dvi - network-cable all connected to the d6000 station as soon as i move the mouse a bit and do some window-work, the cpu-load goes through the roof. And this is even true, when i connect the mouse to a normal usb-port directly on the laptop. With the mouse on the normal usb connected, if i move the mouse, the display link cpu-load goes through the roof, even if the mouse is not connected to it (as seen with linux top-command) Last edited by bhuber; 01-16-2020 at 03:40 PM. |

I also have this issue.
Xubuntu 18.04 Kernel Version: 5.3.0-26-generic DisplayLink Version: 5.2.14 I use an NVIDIA GT 650M with nouveau Processor load of DisplayLinkManager process (with one 2560x1440 60Hz monitor connected) reaches 14% to 40%, when moving mouse it reaches around 200% in sum. Load is similarly disastrous when watching videos. I used htop to look at load. I have 2 cores and 4 threads so this impacts cpu performance immensely! Is this supposed to be normal behavior or can we expect a fix? |

high CPU usage on linux
Hello,
I also have huge CPU usage making the laptop unusable -- when stuff moves on the screen. My setup: - Dell XPS 13 - linux - gnome - X - latest displaylink software - i-tec USB 3.0 / USB-C Dual 4K Dock Is there anybody from DisplayLink who could eventually give some hint on this issue that seems to annoy several users ? I will have to sell my docking station if no solution are provided :-( |
