Linux 5.9 and Display Link

[drlele]

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

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...

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

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

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