displaylink-debian VS install-waterfox-linux

That is exactly it, proprietary driver. I use https://github.com/AdnanHodzic/displaylink-debian with excellent results with my Pluggable brand USB dock.

The monitor works fine with Windows 10 after I install the drivers. With the Ubuntu, however, things do not work. I tried installing the driver suggested by ASUS specific for this model, the most recent official Display Link driver, and the community script. All have give the same result: installation is said to be successful and asks me to reboot. I reboot and connect the screen. Screen turns on and keeps black. No display is detected. In Additional Drivers there is no drivers listed.

u/marvelggg was correct the issue was DisplayLink. Unfortnuately it wasn't possible to just reinstall their driver because they are not up to date with the current Linux kernel. I used calebanthony's advice from this page to get me back on track;https://github.com/AdnanHodzic/displaylink-debian/issues/745

If you use an Ubuntu or Debian based distro here is a DisplayLink driver: https://github.com/AdnanHodzic/displaylink-debian

(The lenovo branded dock is most horrible especially when used with Linux - needs drivers to be install. https://github.com/AdnanHodzic/displaylink-debian All others just work).

I bought a DisplayLink dock for my ubuntu laptops (2015 XPS and 2021 XPS) and it doesn't really work with either. It's quite maddening.

It requires a strange driver I would've preferred to avoid. I tried a strange workaround on both and neither really works; one still doesn't display through the DisplayPort or HDMI, the other doesn't work with the M.2 2280 built into the dock.

Latest installation script is at https://github.com/hawkeye116477/install-waterfox-linux/releases and instructions at https://github.com/hawkeye116477/install-waterfox-linux#instructions.

I created graphical application, which installs and uninstalls official tarball and AppImage packages of Waterfox, especially for Windows OS veterans, who are new in Linux world. Currently it works only for one user. More details and download at https://github.com/hawkeye116477/install-waterfox-linux/releases/tag/gui-v1.0.0.

I wouldn't recommend installing by myself on root directory and automatic updates on root directory rather won't work properly. If you want on root, then maybe better would be to install one of my packages => https://github.com/hawkeye116477/waterfox-deb-rpm-arch-AppImage#adding-repositorydirect-download. However if you want on user directory and create shortcuts and other extras, then script https://github.com/hawkeye116477/install-waterfox-linux is great helper for this.

You can use script from https://github.com/hawkeye116477/install-waterfox-linux to install official tar.bz2 package from site.
