The issue is discussed here: https://github.com/DisplayLink/evdi/issues/225


Get:
1. Unzip the DisplayLink package and extract the inner archive

Code:
unzip 'DisplayLink USB Graphics Software for Ubuntu 5.3.1.zip'
chmod +x displaylink-driver-5.3.1.34.run
./displaylink-driver-5.3.1.34.run --noexec --keep

2. Patch evdi-1.7.0 with #228 or clone directly

Code:
tar xf v1.7.0.tar.gz
pushd evdi-1.7.0
patch -p1 < ../228.patch
popd

or

Code:
git clone https://github.com/DisplayLink/evdi.git evdi-1.7.0
pushd evdi-1.7.0
git fetch origin pull/228/head
git checkout -b pr228 FETCH_HEAD
popd

3. Replace evdi

Code:
rm displaylink-driver-5.3.1.34/evdi.tar.gz
pushd evdi-1.7.0
tar cf evdi.tar.gz *
cp evdi.tar.gz ../displaylink-driver-5.3.1.34/
popd
4. Install displaylink

Code:
cd displaylink-driver-5.3.1.34
sudo ./displaylink-installer.sh install
However, we did not get feedback from any reasonably skilled Ubuntu user that these instructions are complete for Ubuntu.

The patch has been sucessfully tested on Archlinux and openSUSE.
I followed these commands in Ubuntu 20.04.01 and I had no problems until I tried to install the drivers and I got this:

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, 5.9.7-050907-generic.
This is a fatal error, cannot install DisplayLink Linux Software.
May the 5.9.7 kernel version to be too high?
