Support of proprietary NVIDIA driver
On my Ubuntu 20.04, Thinkbook 16p 2Gen, ThinkPad Hybrid USB-C+USB-A Dock combination, DisplayLink driver 5.5.Beta works at least for a hdmi 2560x1440 display together with the proprietary NVIDIA driver version 510.47.03.
Setting the displays via the kde control panel was not so easy and robust ... with "nvidia-settings" impossible.
It's okay for me now. So, many thanks for the driver. :-)
Displaylink driver 5.4.1 did not work at all.
Is it a coincidence or luck that 5.5.Beta works with the proprietary NVIDIA driver?
Is an update to DisplayLink Release: 5.5, Mar 9, 2022 a risk?

While I am quite content with open-source nvidia (nouveau) driver and Displaylink right now, this set up is not sustainable.
The reason why nouveau driver only support is not sustainable is not exactly Displaylink's fault: the lack of progress in nouveau driver is actually the real cause of the pain: nouveau driver's progress has been so slow that much of NVidia's functionalities, such as video codex, and much more critically, machine-learning aspect of Nvidia can't be used when nouveau driver is used.
As result, people who want to use GPU to accelerate machine learning can't use Displaylink device at the same time.
Moreover, the ground itself is shifting: we are currently in a strange phase which wayland might replace xorg but progress itself is being slow.
I understand the asking Displaylink to support proprietary driver is kind of tricky in such complicated circumstances. But at the same time, I really like Displaylink's product and I have bought a couple devices for my family members, I really hope Displaylink can find a way in which I can use the full potential of my Nvidia hardware as well as the full potential of the Displaylink hardware.

I am currently using 5.5 on Manjaro Linux and had to dig into xorg conf files directly to get the two GPUs to get along. I did a small write-up on the Arch forum that should apply to most Linux distros: https://wiki.archlinux.org/title/DisplayLink#DisplayLink_and_NVIDIA_dGPU_on_X11_(Optimus+DL)
