But by accident I discovered something else, audio provided by the docking station is not as jerky as the native laptop's headphone output. Small win, I can now use the external screens to do some tasks Edit: It's not completely fine, I can still hear cracking when window displayed on the external screen refreshes it's content @any_displaylink_dev Are you aware of the performance issue on AMD systems running 20.04? I see that "1fps when laptop screen disabled" bug got some attention and there is a work going on it. I don't know if the problem I am facing is related to it or no. If you want I can provide more data Last edited by fitter; 09-10-2020 at 07:49 AM. |

For Ubuntu 20.04 they provide a package with a temporary fix. Just google or search around here. |

Latest kernel
I forced my system (20.04) with the latest kernel available.
With the latest kernel from apt-get dist-upgrade (5.4) still had problems, then used this script to get kerlnel 5.8 and now works fine. Only side problem is that my vmware and virtualbox stopped to work because no drivers available for this kernel. Great oppurtunity to learn 'virt-manager' qemu kvm stuff ...

I am not very familiar with kernel development, but since 5.4 is LTS, used by the most popular Linux distros rn and affected by nasty displaylink bug which was fixed in later kernel versions. Shouldn't it get the fix backported then? Ah, btw. I tried installing proprietary AMDGPU drivers to check if it fixes anything - no changes at all... Last edited by fitter; 09-26-2020 at 12:57 PM. |

I'm going to try the special Ubuntu xserver-xorg-core version stickied to see if that helps but at least I can see my AOC USB 3 monitor now on one Linux distribution finally so thanks EDIT - All is working well the latest 5.8.12 kernel with no high cpu usage. I installed the kernel via the mainline 'app' plus the latest displaylink-driver-5.3.1.34 from Display link direct on Kunbuntu 20.04 LTS Last edited by andy_g; 10-03-2020 at 08:06 AM. |

I have recently upgraded from Linux Mint 18.3 (Ubuntu 16.04) to Kubuntu 20.04. The improvement I see in DisplayLink behavior is noticeable: no more screen corruptions even if I use the OpenGL compositor and VSync, for instance, and no apparent performance issue (the video seems to work just fine, like if I had the monitor connected directly to the HDMI port of my notebook).
However, what is not working is audio: even if I have the output in Kubuntu audio panel ("USB3.0 Dual Video Dock") and even if I try to change the output profile to anything listed there (from digital stereo IEC958 output to analog stereo, 2.1, 5.1, what else output), I hear no audio neither from headphones connected to the audio jack in the front of the docking station, nor from the speakers of my monitor connected to the docking station through HDMI. Has anyone this problem? |

Sometimes you won't notice it, but sometimes it slows down the system a lot... The audio problem remains, too. |

Today I have closed my laptop screen, just to try. And guess what, no lag anymore. Is this problem finally fixed? Running Ubuntu 20.10 with latest updates.

Am attempting to get Displaylink USB/VGA adapter to work on Ubuntu 20.04 with NVIDIA Card. I have filled my video ports with three monitors and need to add a fourth. I have installed Ubuntu driver from Displaylink site and upgraded with xserver patch for 20.04. Still no joy. lsusb "sees" the Displaylink as:
Bus 001 Device 004: ID 17e9:4300 DisplayLink Displaylink USB3.0 Display but no action on the attached monitor. Am using CableCreation Adaptor. Attached is the Linux Support tool zip file. Any help would be appreciated. Thank you. |
