For those interested:

This was the link to my installer using the fix that was working fine for 5.10.4

https://github.com/robotard/setup-ub...kdownloader.sh

Shouldn't be private now...

Ooh, not intentionally, but just a note that the EVDI one is broken again on 5.10.5...Works fine on 5.10.4 though...

What changed, in simple terms :confused:

Hope that helps.

Just tried this on Kubuntu 20.04.1 with kernel version 5.10.0 and got:

Code:

DisplayLink Linux Software 5.3.1.34 install script called: install

Distribution discovered: Ubuntu 20.04.1 LTS

Unsatisfied dependencies. Missing component: Linux headers for running kernel, 5.10.0-051000-generic.

Trying to install kernel 5.10.2 now...

Different issue on 5.10.2: it seemed to install fine but couldn't find the evdi 1.7.2 binaries. Sadly I lost the log, will try again later.

Hey all

Just to let you know everything is now working fine again on the latest 5.10.9 kernel for me after not working on 5.10.5 but working on 5..10.4 as per my earlier post.

Did you install normally or with the method from this thread?

If with the method: which evdi version did you use?

It works now!

Finally it worked with kernel 5.9.16 and with evdi 1.7.x on my Thinkpad T490!

Neither 5.8 or 5.10 worked at all with the same procedure, so I guesse trial and error was necessary :D

Anyone got it to work with 5.11.2 ??

I could do everything just fine until recently when I upgraded my kernel to 5.11.2

I can't even install evdi anymore...

Code:

DisplayLink Linux Software 5.3.1.34 install script called: install

Distribution discovered: Pop!_OS 20.10

Can at least install now

I was able to install it using the changes of this PR.
https://github.com/DisplayLink/evdi/pull/269

Code:

unzip 'DisplayLink*.zip'

chmod +x displaylink-driver-5.3.1.34.run

./displaylink-driver-5.3.1.34.run --noexec --keep



git clone --branch linux-5.11-ftbfs-fix https://github.com/piso77/evdi.git

cd evdi 

tar cf evdi.tar.gz *

cp evdi.tar.gz ../displaylink-driver-5.3.1.34



cd ../displaylink-driver-5.3.1.34

sudo ./displaylink-installer.sh install

Displaylink yet not working....
evdi is installed and DisplayLinkManager running.
