Got to a random temporary folder, clone and build from source:

Code:

cd <temp-folder>

git clone git@github.com:DisplayLink/evdi.git

cd evdi

make

List all installed versions of evdi: ("evdi/<version>" is what you are looking for)

Code:

dkms status

Uninstall current version of evdi (if the latest version (currently 1.12.0 is not installed at all, this step is unnecessary)), if you want you can uninstall earlier versions, too

Code:

sudo dkms remove -m evdi -v 1.12.0 --all

Create the dkms source folder and copy the newly built files into the dkms folder:

Code:

sudo mkdir /usr/src/evdi-1.12.0/

cd /usr/src/evdi-1.12.0/

sudo cp <temp-folder>/evdi/module/* .

Code:

sudo dkms add -m evdi -v 1.12.0

sudo dkms build -m evdi -v 1.12.0

sudo dkms install -m evdi -v 1.12.0

If after a reboot, it does not just start working, re-run ubuntu installer (from and following the instructions https://www.synaptics.com/products/d...wnloads/ubuntu):

Code:

....

sudo ./displaylink-driver-5.6.1-59.184.run

These instructions worked for me on Fedora 36 with kernel version 6.0.5-200. Thank you so much for the help!

What is the link to buy the dual hmi usb?

Hello, One question, it actually helps....
I have questions about which hub should I buy to use dual hdmi, could anyone tell me which is the right device?

I use PopOs.
I've seen people talking about this wavlink, but I don't think it's him:

https://pt.aliexpress.com/item/10050...d=yHr0am7r1rPL

Can someone confirm if this is the one, or what is the correct link?
Note: I'm in Europe.

Hello @kellehorreur, first of all, thank you very much for doing the verbose explanation, for a not so advanced linux user like me, this makes is super easy to follow and understand.

However I am facing a challenge that you may be able to explain/solve.
I am using Fedora and my asus Zenscreen was running perfectly on kernel 5.16. however, I just updated to Fedora 37 running kernel 6.0.12-300.fc37.x86_64 and the problem I am facing is that when I try to compile evdi, it always comes back with an error saying that it couldn't find libdrm/drm.h

Code:

evdi_lib.c:6:10: fatal error: libdrm/drm.h: No such file or directory

    6 | #include <libdrm/drm.h>

      |          ^~~~~~~~~~~~~~

I checked and the latest version libdrm is installed but I guess it just cant find the right path??

would you have any idea on how to fix this? :confused:

cheers, and thank you very very much in advanced

Well, I kept digging around online and after a lot of trials I found this response from somebody on reddit:

This post

Code:

cd ~/Downlaods 

git clone https://github.com/DisplayLink/evdi

cd evdi-devel/evdi/module/

cp * /usr/src/evdi-1.12.0/

sudo dnf install dkms

sudo dkms build -m evdi -v 1.12.0 --force

sudo dkms install -m evdi -v 1.12.0

sudo reboot

and it worked like a charm. didnt even have to reboot and my Asus ZenScreen came back to life.
and in case somebody is wondering I am using Fedora 37
Linux fedora 6.0.13-300.fc37.x86_64

hope this helps somebody else.

cheers!

What is the status of DisplayLink drivers vis-a-vis newer kernels, such as 6.1.4? And just because my head spins after reading this thread, would any of the participants care to summarize the bottom line in this matter please?

To make it simpler, here's what the great unwashed want to know:

Can 5.6.1 DL drivers be installed on newer kernels such as 6.1.4?
If yes, what would be the definitive procedure?

Many thanks to all participants for their contributions so far.

The DIsplaylink itself doesnt change that much so if you already have one installed you just need to update evdi ( https://github.com/DisplayLink/evdi )

Before updating to a 6.0+ kernel you just have to replace the the files dkms should compile.

Code:

# Download the most recent evdi module

$ git clone https://github.com/DisplayLink/evdi 



# Replace the ones installed by the displaylink installer

$ sudo cp "./evdi/module/*" "/usr/src/evdi-1.12.0/"



# (Optional! ) If you are already on a 6.0+ Kernel ( thus the dkms build failed during the upgrade ) reinstalll the module for your current kernel

$ sudo dkms build -m evdi -v 1.12.0 --force

$ sudo dkms install -m evdi -v 1.12.0 --force

In case youre on Fedora you can just download the asset and install it with dnf:
https://github.com/displaylink-rpm/d...s/tag/v5.6.1-1

Its already upgraded to support Kernel <6.2
6.2 will need another ( tiny ) update as well -> https://github.com/DisplayLink/evdi/issues/394

@crashdummy: many thanks! Worked like a charm!

Saved this gloomy Monday

I was on Linuxmint 21.2 victoria with kernel 5.19.0-50 (Dell XPS 9320 + UD22 Dock + 4 monitors). I decided to upgrade to 6.2.0-26 this morning (I don't know why).

Unsurprisingly, 2 out of 4 monitors stopped working.

Then I found this post and started following along. Interestingly, at the "Register the dkms module" step, right before I was about to execute

Code:

sudo dkms add -m evdi -v 1.12.0

everything went black. It seemed the system did a auto-log-out. Then all 4 monitors started working just like before!

Thank you sire!
