Support Ubuntu 20.04 LTS (Focal Fossa)
 
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:

Code:

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...

gvart 03-12-2020 04:48 PM

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:
Quote:

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...

djkajo 04-17-2020 09:00 PM

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 ?

If you look into the log you can see the flex command is not installed, install by

Code:

sudo aprt-get install flex
But next you will get an new problem and another and it will fail anyhow.

An option I used is https://www.displaylink.com/downloads/file?id=1369 it possible to run and get DisplayLink to work for 20.04 version.

polrus 04-24-2020 06:02 PM

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 :/

in version 19.10 it works more or less
 
works on 19.10 when you upgrade to 20.04lts to stop working.

smhanov 04-24-2020 08:39 PM

Ubuntu 20.04 solution
 
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/displ...ian/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 !!

Thank you djkajo!

I can confirm it worked for me on my dell XPS and Dell D6000 dock following the instructions that you followed as well.

I hope that solution works for everyone here!

Not working after upgrade from 19.10 to 20.04
 
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.

20.04 choppy graphics and sound
 
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

Its about time! Saw it too and if already published, the driver should be available for download asap...

Have 2 of the docks and would be very disappointed if it would not be supported anymore..

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/know...ent-x-upgrades
But the troubleshooting is already installed but doesn't work

Do you guys having the same problem ?

Worked for me with the 20-displaylink.conf as described in your link. However Wayland produces significant tearing, fine with X11 though...

try to use just your second monitor and check if it is working well. I don't have problem when i extend or duplicate my screen. Only when I use the monitor alone it happens

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.

New driver now available and installed - builds/installs just fine under 20.04 and works a treat with both X and Wayland. :-)

Missing Component libdrm
 
Today I want to install the lastest ubuntu driver. But I get the error. Missing Component libdrm. But it is installed. Anyone have the same issue?

You need to make sure both libdrm-dev and dkms are installed: "sudo apt install libdrm-dev dkms"...

Yep. Both are installed. I uninstall both an let the installer install them, but that don't work too.

Would you like to post your output? Also "lsb_release -a", "uname -a" and "apt search libdrm-dev"

Same here, I was able to install 5.2 using github link given before, but I can't install 5.3, I got same error.
Tried to re-install dkms and libdrm-dev, with no success
