Last year, after DisplayLink released the first version of the supporting tools for their USB3 chipsets, I tried it out on my Dell S2340T.

As I wanted a clean way to test new versions, I took Eric Nothen's RPMs, and updated them along with newer versions, automating the creation of 32- and 64-bit x86 versions.

The RPM contains 3 parts, evdi, a GPLv2 kernel module that creates a virtual display, the LGPL library to access it, and a proprietary service which comes with "firmware" files.

Eric's initial RPMs used the precompiled libevdi.so, and proprietary bits, compiling only the kernel module with dkms when needed. I changed this, compiling the library from the upstream repository, using the minimal amount of pre-compiled binaries.

This package supports quite a few OEM devices, but does not work correctly with Wayland, so you'll need to disable Wayland support in /etc/gdm/custom.conf if you want it to work at the login screen, and without having to restart the displaylink.service systemd service after logging in.

The source for the RPM are on GitHub. Simply clone and run make in the repository to create 32-bit and 64-bit RPMs. The proprietary parts are redistributable, so if somebody wants to host and maintain those RPMs, I'd be glad to pass this on.
