How to install DisplayLink software on Ubuntu 20.04
The new DisplayLink
driver for Ubuntu features an improved installer, that aims to perform the
installation process in a single step if possible.
The installer should be started with administrative privileges:
The installer is going to check for dependencies automatically, and
execute apt package manager when needed.
apt update has already been called, it might ask to update
the package list first:
or proceed directly to package installation. Permission should be granted by just hitting ENTER.
The messaging may vary depending on the packages already installed in
the system. Either way, ENTER should be pressed to proceed.
The packages required by the driver are dkms and libdrm-dev.
The first one is needed to enable loading of EVDI module.
The latter is required due to libevdi being shipped as source code and build during the installation.
Should the permission to install the packages not be granted, the installation process stops.
In such case, either please restart it and allow to install the missing packages, or install them manually by executing the following commands (and agreeing to install the suggested packages):
sudo apt update
sudo apt install dkms
sudo apt install libdrm-dev
