I am try to install displaylink driver in Ubuntu 20.04 LTS (Focal Fossa)
(linux kernel 5.4.0-14-generic), but the instalation finish with the error:

make[1]: se sale del directorio '/usr/src/linux-headers-5.4.0-14-generic'

It planned some new release to fix this problems?
Thank! Regars

With Ubuntu 20.04 due out in the next month, I would be most interested in beta testing any new drivers that support this release...

I'm facing same issue after upgrading from 19.10 to 20.04
Displays are not working anymore and I'm not able to use them at all.

For those who in the same situation, you can use an opensource drivers which worked for me https://github.com/AdnanHodzic/displaylink-debian

The displaylink-debian definitely installs focal based drivers (it shows as it installs):

During the installation it downloads from our friendly neighbourhood DisplayLink webpage:
https://www.displaylink.com/downloads/file?id=1369

DisplayLink Linux Software 5.2.14 install script called: install
Distribution discovered: Ubuntu Focal Fossa (development branch)

The github page where you likely found displaylink-debian also mentions that it downloads from the displaylink site then does some patching and installing of items...

I'm still trying to iron out some things as am new to displaylink, but hope this helps...

Same situation here, just upgraded to 20.04 and the secondary display stoped working, i use a thinkpad dock connected to the laptop and got it to work on Ubuntu 19 with the latest displaylink driver, now even reinstalling the driver it does not work.

I have tried the open source drivers advised here but even after following all the steps it does not work either.
Any update soon ?

I have the same issue

I installed flex, bison, libelf-dev
but still the installation fails.

I bought 3 x displaylink devices last week - pls support and update the driver for the newest kernel

Also it is a shame that in 2020 and Ubuntu 20.04 installation instruction is dated 2014 and mentiones ubuntu 14 :/

This is confirmation that following the instructions on https://github.com/AdnanHodzic/displaylink-debian works with Ubuntu 20.04.

With the official drivers, even after installing flex and bison, it will not work because the makefile cannot find Build.include in the kernel headers.

After running:
sudo apt install git
git clone https://github.com/AdnanHodzic/displaylink-debian.git
cd displaylink-debian/ && sudo ./displaylink-debian.sh

Then, reboot, and "delete all secure boot variables" in bios or otherwise remove secureboot.

Hi Smhanov.
I've followed these instructions without success. I've reported here: https://github.com/AdnanHodzic/displaylink-debian/issues/391

Please, Could you share more details here.
What does mean `delete all secure boot variables` ?.

Regards.

I can confirm it also worked for me.
I did the above steps, rebooted, checked if secureboot was disabled (it was), when ubuntu booted the secundary screen started working.
I have the secondary screen connected to a Lenovo Thinkpad x1 thru a Thinkpad Dock.
Thanks !!

I have tried the displaylink-debian but it has errors - HUNK failed
I am wondering whether it would work if i did a fresh install of 20.04
I am wondering if someone has instructions for completely removing the official DisplayLink driver before trying displaylink-debian
I have a Thinkpad with Intel Graphics

I have the same issue, Intel Thinkpad, worked under Eaon, did a fresh install of Focal, managed to get video working with help from here. Then Focal got an update yesterday (pretty sure I saw EVDI name in packages being updated) and now no video. Previous fixes not working :(
You could try a fresh Linux install, but as soon as it tries to update I suspect you'll hit the same issue.

I really wanted to try scaling too - why no word when new official drivers will be released? We shouldnt really need to compile them ourselves either.

Got the displaylink working on 20.04 @ amd and vega graphics and wayland. I had to install libdrm-dev to avoid the drm.h error while running install from the git clone. Now everythings fine other than the graphics and sound seem to be slightly cutting off and choppy. Anyways 100% better than without it.:p

I followed the procedure and It worked well. the only problem I have with my ThinkPad Hybrid USB-C with USB-A is that I have a pageflip issue as described :
https://support.displaylink.com/knowledgebase/articles/1181623-displaylink-ubuntu-driver-after-recent-x-upgrades
But the troubleshooting is already installed but doesn't work

Do you guys having the same problem ?

Mmm not sure why I would do that - I have 3 monitors, 2 driven direct from the PC (one HDMI and one DVI) and the third via the DisplayLink (USB3 to DVI). If I switch off the two main monitors, the third (DL) monitor continues to funciton correctly. If I make it my primary display and reboot, then login (blind, as the login screen doesn't display on my DL monitor), then again the performance is fine. Doesn't really prove anything to be honest unless I start unplugging monitors....(CBA!)

In any case I am happy for now with X11 and have all the functionality I require...we'll see what the new driver is like once its released.

Only thing extra I had to do even though on Intel graphics I
had to make /usr/share/X11/xorg.conf.d/20-displaylink.conf
contain:
Section "Device"
Identifier "DisplayLink"
Driver "modesetting"
Option "PageFlip" "false"
EndSection

not this:
Section "Device"
Identifier "Intel Graphics"

I ran into the same issue(displaylink-debian downloading 5.3) but it can be easily fixed by replacing head -n 1 on line 21 and 23 of displaylink-debian.sh with sed -n '2p' so the script grabs the second download link. Works for me, finally got my 2 displays working. 5.3 didn't work at all for me.

Dear users!

Thank you for your constant communication here on the forum and your patience.

We would like to apologize for the inconveniences that you have faced while trying to use our new driver.
We are aware of libdrm issue on our new driver for Ubuntu 20.04

Right now our Engineering Team is working on the resolution of the problem. We should be able to release a fix very shortly as our engineers are already testing the possible solution for this case.

As a possible temporary workaround you may start our installer in this manner:

From console:

Installing Workaround:

LC_ALL=C sudo ./displaylink-driver-5.3.0.28.run

Uninstalling Workaround:

LC_ALL=C sudo displaylink-installer uninstall

This should help you for now before we have a permanent fix done.

Thank you very much for help in developing our drivers and I will be posting here any new information we would be able to share with you!

Kind regards,
Jakub

Confirming there is still an issue with the latest package for Ubuntu 20.04. I recently upgraded 20.04 and installed the latest DL package, displaylink-driver-5.3.1.34. Now if I close the lid, the UI lags 3-5 seconds on input (e.g. button click does nothing for 5 seconds). Opening the lid and the issue immediately goes away. Nothing from htop seems to indicate this is in anyway tied to CPU/memory load.

Interestingly the mouse movement does not lag. Just the click and keyboard. This happens even though mouse/keyboard is not connected to the dock. Dual monitor setup. Does not matter if lid is open or close.

I would be happy tho share the logs gathered with displaylink tool on priv to DisplayLink support. I'm not comfortable to share anything gathered using 'sudo' on public forum.

05-11-2020, 11:19 PM

Confirming same issue here.

Running Ubuntu 20.04, with a StarTech DK30C2DPPD dock (DisplayLink chipset: DL6950) and ThinkPad E590 and DisplayLink drivers 5.3.1.

When connecting via the dock to an ultrawide monitor (LG 38 inch), with native resolution of 3840x1600, it is extremely laggy - every mouse click action takes 3-5 seconds - it completely unusable.

If I switch back to just use Laptop display (dock still connected, but monitor setting set to laptop screen only), everything works perfectly fine.

CPU load seems a bit high, but not massively high.

When on Ubuntu 19 and using the previous driver, I had exactly the same issue plus CPU was even higher (htop was maxing all threads at 100%).

I have set the logging to 1 (as per https://support.displaylink.com/knowledgebase/articles/1107401-how-to-reduce-or-increase-the-amount-of-messages-t) but made no difference.

Have also amended the 20-displaylink.conf as per a lot of other threads, again with no difference.

On a smaller monitor (34 inch with native resolution of 3440x1440), it performs better but still unusable.

Keen to see if DisplayLink update the driver soon.

UPDATE

With EVDI logging set to 0, DRM logging set to 0, pageflip modsetting applied (https://support.displaylink.com/knowledgebase/articles/1181623-displaylink-ubuntu-driver-after-recent-x-upgrades) AND (important AND), the external monitor set to extend mode, the lag is significantly reduced - almost usable!

If I change the display settings to external screen only (i.e. single display, laptop display off), then the massive lag instantly returns.

So, the primary (laptop) screen needs to be on and active for the lag on the external monitor to be 'acceptable'. This seems like a really strange bug.

Anyone else experience this?

Stofe7

05-12-2020, 10:40 AM

@rjbathgate, can you compare with "mirror" settings please? I curious about your case.
In my case if I choose mirror, then it will be a kind of usable scenario, but of course I lost the external monitor highest resolution. So the exact case is, Linux screen mode is mirror, resolution is set to the highest one of the internal screen, lid off.

Dear friends,

I have been experiencing this issue for quite some time, since I run Arch Linux (rolling-release with always the most recent updates) therefore I run into these problems often and always very early.
I have identified this problem already over a month ago.
This seems to be a problem with the evdi-component that is installed with the displaylink driver (it's a dependency).

Someone has reported this upstream (with the Displaylink developers), since the displaylink driver depends on it.

@JakubDabrowski and @mlukaszek (Michal)

PLEASE REACH OUT TO ME. I'M HAPPY TO COLLABORATE TO GET THIS FIXED WITH YOU.

Here's the link to the evdi-bug report:

I use a displaylink device (HP portreplicator 3005pr) to switch between Ubuntu desktop and windows laptop. Two monitors.
Issue with the desktop: clean install Ubuntu 20.04 and following displaylinks installation instructions for 5.3.1 driver. Works fine with one monitor connected to video out on the desktop and one one displaylink device.
Both on the displaylink device mouse movement okay, but reactions on actions to slow, serveral seconds (>5), reaction on typing also lagging behind.

Second try: clean install Ubuntu 20.04 and following display link instructions, but instead of libdrm-dev I used the non dev version. same behaviour, but reactions speed now increased tot a lag of 3 seconds when alle displays are on the displaylink device.

I seem to have the same issue on Xorg, even when I have an HDMI screen as well as a DP screen connected, but with the laptop lid closed. When I switch to Wayland it's much better but the input stalls frequently leading to input being repeated a number of times.

I'll wait until the patch comes out to see if it helps but I see latency on the same dock with the same devices connected on Wayland with the laptop display in use, so it may be that this is the most obvious issue currently but that there may be a lot of other issues to resolve at the moment.

I just installed the USB to HDMI extension to may Ubuntu 20.04 LTS. Installed displaylink-driver-5.3.1.34.run. It's a thinkPad laptop with closed screen which is connected through docking station to one DisplayPort screen and one VGA screen.

The USB screen is displaying correctly.
The issue i have is that as soon as i use mouse the cursor starts to jump around and sometimes pixeling. I can't perform basic operations like grab and drag as the cursor location changes. When not using mouse it seems to be stable.

Changing the refresh rate for the USB to HDMI screen from 60 to 50Hz decreased the scale of the issue a little bit, but the problem persists.
Tried to move the mouse to another USB port and even change the mouse

Is there any solution for that ?

I am using Ubuntu 20.04, Wayland, an rx5700

Installation was a breeze, however performance is very bad. I am on a dl 6950
On Windows performance is great, here however it's not usable.

I am using Wayland.
Monitor setup:
Left: 1080p Potrait
Center: 1440p 144hz (On primary gpu)
Right: 4k 60hz

This is a desktop system, I can plug all the displays into the rx5700 and it works fine, but I am testing this device.

I have same issue on a laptop with AMD GPU : the second screen (using DisplayLink) is detected but the display is very jerky

Having the same exact issue with AMDGPU + DisplayLink as well.

My workaround has been to stay with Ubuntu 18.04 using the DisplayLink 5.3.1 driver for Ubuntu for the time being alongside the AMDGPU-PRO driver as that seems to be the only working configuration for me, but it's not ideal, especially considering I'm having to use the AMDGPU-PRO driver which has had compatibility issues with running software that works fine using the AMDGPU open-source driver. The lack of proper support for AMDGPU is what's keeping me from upgrading to Ubuntu 20.04 LTS and it seems like this issue has been brought up my numerous people for a few months now with no real answers or estimations on progress. :confused:

I would definitely advise DisplayLink to make their drivers fully open source, as many others have suggested over the past several years. That way, you know, us pesky Linux users wouldn't have to be so much of a bother. ;) I think it'd be to their benefit anyway, it's not like open source contributors would be seeing any of the profits DisplayLink makes and if anything it'll help to get their software available on more platforms which ultimately results in greater revenue for them.

I just realized that all displaylink developer replies were about "1FPS problem" when laptop screen is off. I failed to find any mention of screen lag for external monitors problem. Which is a little bit worrying me. Nevertheless we have vacations season rn, lets hope this topic will be addressed soon.

I could even live some time with lagging external screen, I can just display there some static things and mainly work on my laptop screen. But this problem also affects my laptop's audio, which gets some hiccups. I cant accept it unfortunately...

Yeah, I'm aware. The latest 18.04 kernel using the latest DisplayLink driver for 18.04 did indeed break DisplayLink with AMDGPU, which is the main reason I'm using the 5.3.1 DisplayLink driver as it's an older version that seems to be working fine with the latest kernel alongside AMDGPU-PRO.

Without these workarounds, my external monitor exhibits high latency and really bad screen tearing. The monitor behaves fine with AMDGPU-PRO, so I doubt the fix is impossible. Hopefully some sort of update is given soon considering it seems to be affecting AMDGPU users as a whole and is likely keeping some, like myself, from updating to Ubuntu 20.04 LTS.

Small update. Ubuntu 20.04 got minor kernel update recently, so I decided to install the displaylink driver again and check if it fixed the external screen responsiveness (it didn't...).
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

Got the same 1fps thing here with Nvidia hardware. I can only assume that the OS tries to save power and trottles the GPU or the USB controllers. I tried to prevent this but no success. Any ideas here?

The DisplayLink staff is working on getting fixes merged into Xorg-Xserver.
For Ubuntu 20.04 they provide a package with a temporary fix.
Just google or search around here.

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 (https://linuxconfig.org/how-to-upgrade-kernel-to-latest-version-on-ubuntu-20-04-focal-fossa-linux) to get kerlnel 5.8 and now works fine.
:eek:

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 ...
Good to hear that. 20.04 probably will get 5.8 kernel next month as another point release with stuff from Ubuntu 20.10.

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...

I've been testing Linux again recently and can confirm Release: 5.3.1 05 May 2020 seems to work on my AMD 4800H CPU with Kernel Version 5.8.12-050812-generic although it seems to use more CPU than I would think reasonable - over 30% at times :eek:

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 :p

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

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?

I must partially correct myself. Indeed, after some minutes of usage and when there are many applications open, the DisplayLinkManager process almost constantly eats from 0,5 to 1 full core of my CPU (12%-25% of an i5 Haswell 4-core CPU).
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? :rolleyes: 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.

After latest Ubuntu updates it seems the problem is back, lagging when laptop lid closed.

Most compatibility issues between displaylink, evdi and kernel vers. > 5.8 have been solved by the evdi branch 1.7.x
Instructions for its installation are reported here:

Perhaps this might work for you as well.
If not, feel free to report back.

Problem described here (for those who might come to this thread due to same issue):

https://www.displaylink.org/forum/showthread.php?t=67537

Tried the fix explained here: https://displaylink.org/forum/showpost.php?p=91259&postcount=19

Tried the fix with both 5.4 kernel (default in Mint 20.1) and a 5.8.x kernel (via Update Manager). Neither made a difference. Still just blurry lines in correct resolution.

Totally broken on a System76 GalagoPro with Kernel 5.11.x and DisplayLink 5.4.

Worked without issues on Kernel 5.3 and DisplayLink 5.3, so there must be an incorrect parameter.

Looks as if it's a MESA bug; patch needs to be applied:

It has now been more than a year since DisplayLink provided a patch for this issue. We are now up to xorg 1.20.12. Will this ever get fixed?
